There are tons of threads out there spouting the companions you wish you could kill or never have taken on in the first place, etc.
So, let's change it up. Who are the companions you actually like? Maybe it is one you fell in love with right away or maybe they grew on you as you progressed through their story or maybe it's just the fact that one companion suits your play style of your class particularly well. It does not matter why you like them. Let's feel the love
Whenever I think about my various characters' companions, I invariably think about Kira. This is probably because my first character was a JK guardian tank and she best complimented that role until I got Doc, but even after Doc there were times when killing stuff faster was preferable to being invincible. Further I think the romance was great too.
