Unfortunately I haven't had a chance to play many mods, however Angelo and Irenicus from LR are both fantastic! Hopefully I'll get a chance to experience more NPC's in the future.
Ah yes... I also played Tsujatha... It's a good mod. If - Highlight for Spoilers ----you don't mind romancing him only to find out he didn't reeeeallly care about you, only about that chick he used to love. Yeah. That was awesome. Screw you Tsujatha. Just screw you. ----
Grrrr. So yeah. Can't quite recommend him. If you don't mind what I mentioned then sure, but I won't be playing him again.
