Swoop was my most loved G1 toy as a kid (which I still have).
I was "Team Blaster" during the leadership debacle of the 80's comics, so was not a huge fan of Grimlock (the character). A friend had the toy, which I thought was pretty spiffy, but I couldn't get past him wanting to kill Blaster.

Nowadays tho, I'd probably lean a little more towards Slag.
