I have the same size and model and I am much very happy with it. Haven't tried it for gaming though but for DVD movies its much better compare to my sony 37" S series.
Pros: 1. Very good PQ
2. Deeper black
3. Built in USB port is a must for me because I loved to view pictures and play mp3 directly on it.
4. There is like a touch screen control at the side(vol, channel, on/off and source) which is nice.
Cons: 1. Not very good sound coming from built in speaker
2 . It accumulates lots of dust every second (maybe thats why there is a free microcloth inside the box)
3. It runs hot
By the way, you can also check out the other 32er model of different brand like Sony W series and Panasonic lx800 like you mentioned. For the LG's havent check them.
My suggestion buy it or better yet choose for a bigger size let say 40" series 6 also, here in my place(UAE) there is a promo now for 5,400 dirhams(dont know how to convert it to bahrain currency) for 40" + 22".
Cheers
