I'm not a fan of Titanium Rodimus - overall I'm not a fan of Titanium Series. Those figures aren't designed by Takara engineers and - IMO - it shows.
Although the idea of incorporating the trailer into the robot is ambitious... but yeah, not a fan of Ti Series. I find all of them to be cumbersome to play with too.
Energon Rodimus is a fair figure but a lot of its limitations are due to the sacrifices made for the Powerlinxing gimmick. Unfortunately it was during the time when Hasbro put gimmicks in front of engineering (Armada was arguably worse - but Cybertron was generally better). I like Classics Rodimus; not the greatest Classics toy, but he's a reasonably solid Deluxe figure.
