Obviously agility or brawn can make a droid a combat monster, and intel into a super crafter... What have you specialized in that was the most fun to rp?

Well, I've never played a droid PC, but I did have fun as a GM, with a droid NPC. He was a protocol droid that the PC's found and repaired, however on the mechanics checks, they got a couple threat. So I decided that threat meant he didn't translate 100% accurately. So when I was talking to them, on behalf of the natives, I would occasionally just throw in a nonsensical tuna steak, in the middle of an otherwise perfectly thong sentence. It was very fun to watch the players' faces as they tried to puzzle out what I said. I would also do it the other way around, when they were saying things to the NPC natives. I'd have them occasionally tilt their heads, look at each other confused, and then start talking to themselves, trying to make sense of a misplaced word.

It made for some **** fun conversations with my players.

Brawn for a Mechanic is fun. Only an Intellect of 2 but brawn 4. This is a Droid who fixes ships with Athletics not Mechanics.

Agility and Brawn... but he likes to charm and negotiate...
