ROTF Sideswipe is IMO much better than DOTM, especially if you put the car kibble on the feet backwards when transforming it which fixes stability issues completely. Sidearm Sideswipe looks better but has no blades so you might want to get some from Shape ways for him. Depends on how much you want to spend on him.
Battle Blades Bumblebee is the other /toy/-approved Bumblebee, and it just looks better IMO.
07 Ratchet or DOTM are the best figures of him. ROTF Ratchet tried to be cool with its gimmick but it just sucks.
Best Jazz is the Human Alliance one but it will kill your scale and 07 Jazz is just ugly.
Takara made a Dino out of the Sideways mold and a movie Wheeljack from the Que mold, it's your call if you want screen accuracy or a better looking toy for Wheeljack/Que.
The wreckers will be expensive as fuck to complete since Leadfoot is rare. Roadbuster is crap.
No idea if you want the twins, they have nice toys but they are the fucking twins.
For AOE, I'd wait for TLK before settling with something and meanwhile check third parties for Optimus and Hound. HasTak Evasion OP is pretty good, regardless.
The dinobots are alright.
