We shopped at Home Depot, Lowe's, and Ace Hardware to see which was the best home-improvement store - here's the verdict

I visited the Home Depot in the Flatiron District.

It felt like I was stepping into a warehouse, with high ceilings and industrial lighting. On the left were small products like dish soap and cleaning supplies. To the right was the start of the flooring department.

Home Depot had an astounding selection of everything. There was a huge variety of styles and patterns available for each type of product.

The main level had aisles filled with appliances and fixtures.

There was also a huge lighting department on this level.

Upstairs were model kitchens and bathrooms, as well as consultation centers for customers who need assistance in designing their homes.

In the basement level was the gardening department, which had plants, seeds, flowers, tools, soil, and fertilizer.

There were cleaning supplies ...

... craft supplies ...

... and plenty of paint and paint chips.

Many things in the store were not labeled. There was a directory, and plenty of experts were around to help, but the store was clearly aimed more at home-improvement industry professionals. If you don't know the exact nail or bolt you're looking for, it could be challenging to find it on your own.

That said, there were plenty of services for non-professionals, such as workshops where customers can learn how to do things like stain a patio.

Signs around the store explained that if shoppers find a product for less elsewhere, Home Depot will beat that price by 10%. In addition to price matching, this store offers same-day delivery anywhere in Manhattan, starting at $21. Other Home Depot locations also do this, with prices varying based on the order size.

Home Depot's return policy is generous, allowing a full refund for most items if you bring the receipt and store credit if you don't. Home Depot also offers online returns and in-store pickup for online orders. The store felt geared toward professionals, but it seemed to have everything you would need for a home-improvement project, and all of the employees were extremely helpful.

Lowe's was just around the corner from Home Depot.

The gardening department was at the front of the store, and it was significantly smaller than the one at Home Depot.

Lowe's immediately seemed like it was geared towards people that aren't necessarily professionals. There was much more assistance offered for DIY projects, and everything was well-labeled.

In general, however, the store was underwhelming compared with Home Depot.

There was less of everything offered, from lighting, to tools, to paint.

Like at Home Depot, there were model kitchens and bathrooms on the second level.

It also had a comparable selection of lighting fixtures and flooring. The store felt less industrial than Home Depot, and its products were certainly labeled better.

Lowe's had a design center, similar to the consultation services offered by Home Depot.

Home Depot's and Lowe's return policies were the same, and Lowe's also offered a 10% price-match guarantee.

Lowe's also offers workshops and in-store pickup for online orders. Most of the benefits at the two stores were very similar.

The Ace Hardware I went to was in the East Village.

The store was considerably smaller than Home Depot and Lowe's, and it carried a lot of household items and convenience-store products like hand soap and toys. It was a pretty random selection towards the front of the store.

Ace Hardware had a comparable selection of tools to Home Depot and Lowe's, and everything was clearly labeled in this part of the store. It felt more like a local shop than a chain.

The rest of what was on the first floor was pretty random. There were keys, lumber, cleaning supplies ...

... and an assortment of other random products. While there was a ton to choose from, it was very cluttered, and it could be difficult to find a specific product.

Like at Lowe's, many parts of the store were underwhelming. One aisle was completely empty.

Another aisle, which carried small products like screws, nuts, and bolts, had signs taped to the floor, advising customers to write down the quantity and prices of the items they were buying. They were very easy to miss.

The store carried about the same amount of paint as Home Depot and Lowe's, but it was a mess. One of the shelves seemed like it was about to topple over, and paint cans were everywhere.

The rest of the main level had more general household products like Command hooks and coat racks. It also carried kitchen and bath fixtures. There was less of a selection than at Home Depot or Lowe's, and most things cost under $20.

After making my way through the upper level of the store, I headed downstairs.

The lower level didn't have much to offer. There was a sign stating that the store was being rearranged, which explained some of the mess ...

... but it was still poorly labeled and hard to navigate.

Even though the store had a lot of products to offer at low prices, it was very cluttered and disorganized. Ace Hardware doesn't have a set policy for price matching with competitors, and most of its stores are independently owned and operated.

Ace Hardware had a sign advertising assistance for local businesses. Its shipping and return policies are not advertised anywhere in stores, but it offers next-day delivery, in-store pickup, and returns with a receipt for up to 30 days.

Home Depot was the clear winner among the three stores. In addition to the lenient return and price-matching policies, it was more organized and had the best selection of products.
