There are a few differences but the PQ should be almost identical. But if you can't see it during the daytime..... I have a Toshiba 56" that reflects a lot of glare during the day that I've been dealing with for over four years. Anti glare will be a big consideration in my next purchase.
Smokhead, describe "abit on the large side"? Bigger is better in my opinion and that size room should be able to handle a 62" if you are sitting 10+ feet away.
