i had it on the GBA. coming from Final fantasy tactics the game felt slightly clunky for my liking. maybe it was the complexity or the somewhat drab graphics. I do have TO:LUCT on the vita which i have yet to play. Might get around to it one day. Right now i'm playing Fire emblem awakening and its alright. On CH17 and pretty much every unit is promoted so they can make mincemeat of any fresh recruits. Whilst there are opportunities for skirmishes, its a grind if i was to get all the characters playable. in most FE games, i have a core team and stick with them. I am playing it on casual and i must admit my standards are starting to slip as i make easy mistakes sometimes.
I felt the exact same way coming from Tactics Ogre to Final Fantasy Tactics: especially the class system in FFT felt more clunky.
I tried one of the Fire Emblem games but it felt like you had to do each mission twice because the game loved to throw a twist at you in the middle of a mission. Plus it's pretty easy to screw up your team if you're not using a guide, meaning you have to repeat a bunch more or start over entirely.
