Well I'm from Maryland and I've been keeping fish for years, I've been a loyal shopper at House of Tropicals and couldn't be happier with their service. I will say that I have not found a better aquarium specialty store, in my experience, than House of Tropicals.
I've recently moved to North Carolina for graduate school and brought my tanks down with me. I researched all over the internet and went out to several LFS in the area. I went to all of these places several times to see the health of the fish, the stock and such, before I even considered buying fish. I would go to petsmart to get accessories, cheap stands, filter media, food, etc. Like many of you, I would always check on the fish first, then get whatever I needed. After checking out all the LFS in the area, Petsmart was the only place which constantly had healthy fish. No Ick, no dead fish in the tanks, clean tanks and well fed fish. The other LFS all had sickly looking fish, dead fish in the tanks, and tanks that looked like they haven't been cleaned in weeks. To top all of that off, the LFS were all much more expensive for smaller, unhealthier fish. While my Petsmart doesn't have any rare fish, it's got healthy fish. I'd rather have common healthy fish as pets than spend lots of money on an exotic, rare fish that doesn't look all that healthy.
I think all of this is based upon location. Two of the people at the Petsmart I go to, used to work at the LFS in town, but they came to Petsmart because of how horribly the LFS was run. If you have a Petsmart with employees who know what they're doing, it can easily become a better place to shop than the LFS.
