I personally liked the 1st GoW (only played 1,2 and the PSP titles though). It's more of an adventure, nothing that really warrants a second playthrough in my opinion (I finished it 100% back in the day).
LoS is close but has more freedom in combat as far as I can recall. GoW is also linear, no levels or anything, it's one big trip, so if you want to replay a certain part it's either a new game or a save before that.
GoW2 gave players more freedom in terms of combat but in my opinion a lot of the puzzles were bad, as well as the story overall. Kratos character pretty much degenerates in this game (my personal opinion though).
Overall the games are pretty solid, but I'd compare them to the uncharted games as in they are a big budget trip with really good set pieces but nothing I'd play over and over again. (I did finish 1 and 2 on the highest difficulty out of pure boredom and having nothing else in the genre to play at the time).
i only watched my friend playing the first GoW or the second i forgot, he's a damn good h/s player and most games, it runs in their family, so i kinda believe everything he says about a game..
so when he played the game and i was there, well the game was more flashy than DMC3, kinda catch our attention, and i asked my friend "why the hell would play this stupid game?" --i'm biased, i don't like the barbaric, raw, brute design, and he replied "are you kidding? this game is way better than DMC3", i said to myself "shut the **** up", after that i don't know what to believe anymore, XD..
but seriously i'm biased, kinda hard for me to get myself into something if i don't like one of the most important thing that could get me into it.. and now that you've mentioned LoS have more freedom in combat --i don't know story-wise, i could say those lists i've watched really confuse me, it's all a matter of taste in the end i think..
GoW3 has prettiest visuals. But than it has smallest most boring levels, backtracking, unoriginal bosses, and probably one of worst conclusion final fights.
gee, if i could take your words for it, those are like some of the most important aspecst to judge and they make it #1, huh..
