A comparison for anyone waiting on to see what Zeta came up with. Definitely prefer the robot mode of Zeta as it has less greeble, no ugly backback, and less shell showing on the legs. The hasbro planet mode looks far more impressive though.
I wouldn't mind seeing how much parts forming is involved with Zeta's as their combiners have an insulting amount.
