Product Review Comparison P0156 - Five Shelf Storage Rack (48"W x 24"D x 72"H) (Whalen vs WorkPro)

I found this Whalen 5-shelf storage rack at my local Costco and it has the same dimensions as the WorkPro Shelf I bought online a couple of weeks ago. I decided to buy the Whalen and compare it to the WorkPro.
Here's a quick Pros/Cons list:
1) Whalen is cheaper than the WorkPro
2) Whalen uses solid wood boards for the shelves while WorkPro uses the wire mesh.
3) Both use the rivet support system to hold the horizontal rails to the vertical rails.
4) Workpro design for connecting the vertical rails to make the full 72inch height seems more secure than the Whalen.
5) Whelan has a cleaner finish and looks better.
6) WorkPro is rated to hold up to 800lbs while Whalen is 600lbs. Although I never tested them I highly doubt either can support that much weight.

I'm not affiliated with either company that makes these shelves or with Costco or Amazon except for having memberships to both. I had to buy these shelves with my own money earned shaking my money maker on the mean streets. No compensation was provided by any of these companies to make this review.
