I don't know what the current status of TV's is but the last time I shopped for a midsize TV (32" area), I went with a Sony Bravia, which I used to replace a Samsung. Both are great. My Sony is much more expensive (even after a couple years of purchasing the Samsung) because it has a ton of features I frankly don't use but the picture quality and the things I need are perfect.
Basically, keep this in mind: pick the cheapest one with the best picture/audio quality and the features you need. Mine is 3D and I have no plan on ever using that. Probably knocked the price up a ton, especially at the time. I did notice that Sony's video codecs are seriously lacking though. Plugging in a USB device, you're limited to a very specific list of codecs which I wasn't too fond of. I know for a fact that Samsung's newer TV's have a great feature list and video format/codec support.
