I was really looking forward to these, for the robot modes but alas Hasbro QC strikes again!
Why you would make it so that the detailed chest pieces are covered by mostly terrible chest armour that is mostly used to hold some of the leftover alt mode kibble. On top of that, as Griffin mentioned, Scorponok needs his arms sanded to get his hands on, and half of the Kreons (in my case, Waspinator, Galvatron and Spinister) had stress marks on their wrists straight out of the polybags. Scorponoks arms have a tendency to fall off without much provocation and again as Griffin mentioned, Waspinator and Scorponoks helmets are too long, Spinisters too short.
I've taken all but the essential (for the character) kibble off mine so the can keep the chest armour off. Sunstorm and Galvatron really benefit from this the most.
Overall, pick and choose what you want. Sunstorm and galvatron are my picks, I want to like Scorponok and Waspinator more, but their QC issues really limit their effectiveness.
