Yeah, SAGA is interesting in that, by model count, it's clearly a skirmish game, but the gameplay emphasizes unit tactics rather than individual choices, which I associate with larger scale battle games. SAGA also abstracts individual combat quite a bit. I do like it, but it's an oddball as far as games go.
I personally am a big fan of the "Songs of..." games, although the gameplay there is also fairly abstract. It does emphasize individual fighters over unit tactics, though, and a model's "Quality" (discipline, experience, morale, etc.) is very important, since it influences how much he can do for the turn, and you won't necessarily get to activate every model every turn. But other than that, it's pretty standard movement and combat.
If what you like about Battle Troll is just the individual actions and small-scale decision-making, then Song of Arthur and Merlin would be worth a look, but if it's the detailed game mechanics that you like then it's probably not for you.
