Hmm... I thought I made a reply in here earlier, but either it didn't go through or it was deleted. Didn't say anything offensive, though, so I can't see why it would have been deleted.
I agree with sulmoney that Lost and Heroes really are in separate leagues. Whereas Lost has excellent writing, acting, and extremely high production values all around, Heroes really only gets by on the strength of its story. The acting and dialogue have always been pretty campy, and some people say that's the way it's supposed to be because of the comic book influence, I think that's kind of a cop out. That said, though, the first season of Heroes was extremely entertaining, but I was really let down by the limp finale that didn't even give us the big boss fight we were all waiting for! Season 2 was a trainwreck, but I think the writers' strike may have had a lot to do with that.
Admittedly, though, Lost has lost (ha.) a lot of its initial appeal for me. In the beginning I was under the impression that everything was somehow grounded in reality, because the writers said so, but it's pretty obvious that that's just not true. Don't get me wrong, I'm still an addict, but it's just not as great to me as it once was.
PS. Also, isn't it kind of odd that the Indian guy in Heroes is from south India, but he's named Mohinder? At least they're trying...
