What I've heard is that if the specs are the same, it's the same TV. Some of the times this is done so that you can't compare prices. Other times, they are missing some features. I think you have to look at each model specifically. I also don't think you can recommend/not recommend a TV just on the maker. Just like cars, each company makes some duds and some winners.
I've never owned a TLC but some of their models seem to be very popular. The one you are showing from Wal-Mart does pretty good on Amazon and is dirt cheap for that size.
Here is a professional review where it does ok

From my experience, the biggest thing you need to be aware of is glare. If you can't cut down the light shining on the TV even the best ones will not look as good.
