I can't compare to other vendors, but just on it's own webOS in my LG TV got only one "half" update (3.0 to 3.5 I think) and is essentially abandoned. E.g. web browser was working with constant warnings right from the start and now it's not working at all. WebOS probably was intended to be fast but on LG hardware it is crawling slow and apps are often crashing (and it a pain in the ass to reopen what you were watching before crash). And that's on a 1000-1500$ device (when new). Personally I would stay away from LG TVs in future. Maybe others are just as bad, but I see for myself first.
