>>6717241I had the Nemesis version, and he's alright. The core robot is the best part, especially with his cool sword. Still, the shoulders do get in the way too often to ignore, plus the head is always super mode sized. That wouldn't be a problem if the super mode wasn't that great. It makes him too lanky, restricts his articulation even more, and the partsforming is not fun. The tanker armorup thing is good for that one pose and nothing else.
You're stuck with a small Optimus who's pretty good with a huge head and some power up modes that don't help enough. Maybe I'm just spiteful because I paid 200 freedom fries for a special version, but for the $60 TFSource is asking for the optimus one, you might find those aspects negligible. I'd say if you like how the super form minus trailerpack looks, you'll like him enough for 60 burgers.
