Shadow Broker was my favourite across the whole series - very challenging and with a reduced party that made it more tactical, especially when factoring in the shield and other things that made it trickier than anything seen beforehand. And the cutscenes made it much more entertaining and cinematic than previous battles.

Although I found the battle at the end of Omega one of the most challenging in the game, until I realised I could just run and activate the switches! I'm also a big fan of the Colossus on Haestrom, Kai Leng at the Cerberus base, and the huskified Saren.
