On your list Valkyria Chronicles is definately a good game, one of the most unique SRPG experiences out there. Enemy Unknown, while it has some issues even afer the bug fixes, is a solid game. Not one I usually get that into, mind you, but it's pretty easy to tell the quality and time that went into making it.

If you don't mind trying a different kind of RPG that focus's a lot more on time management and interations with other party members, and doesn't really have the same kind of world saving epic plot of others, Atelier Ayesha is a good one to try out. Especially if you like crafting in RPG's, as to date I don't think there is a game that even comes close to the quality crafting system of Ayesha. If you never liked crafting in RPG's though, stay away. It's pretty damn central to the game as a whole.
