Leia all day. Sid is hot trash imho. Her bonus attacks synergy and stealth makes her viable in top arena teams and great in GW . I run Ben qgj leia Rey and sth and love it.
It basically depends on your main team.. because Sids leader ability crit up goes very well with empire allied built teams granting more critical chance etc.. Same thing goes for Leia but instead its for the rebel allied teams ... So it basically is up to you on your team build.. Hope this helps.
*ps I run with Luminara, Darth Vader, Sid, Anakin and Old Man Ben and its pretty good
Leia is far and away the better choice. Sid is OK early game, but sucks on ice after Lv 60. He has some of the coolest animations, but he's really not very good.
Yeah, go with Leia. Sid was good prior to Protections, but once protections were implemented, and healers slowly started to phase out, his usefulness quickly fell.
