As far as home improvement mega stores go, you've got one of two choices. Lowe's kind of won out by default when they opened this location because it is much closer than HD.
That being said, I would probably drive past HD to get to Lowe's now. The customer service is always good in general and when I have specific questions I always seem to get an expert answer.
I have purchased many tools and appliances at Lowe's and have been impressed with the quality. We did experience a problem with delivery of the first appliance, but it was handled professionally and expeditiously.
I purchased a BBQ and all the materials to build the outdoor kitchen around it. They have an extensive variety of pool cleaning supplies and fencing material, which has made projects around the house convenient, saving trips around town.
My only complaint would be the Christmas stuff went up WAY too early.
