In alt mode only, I think the BIS Rodimus looks poor with the protector set. The difference in colours, the blue windows and the grey tires of BIS Rodimus just looks bad.
With that said, I think BIS Rodimus looks fantastic with the protector armour in robot mode! The different red variations plus gold chrome spoilers really make the character stand out. To me, it doesn't look out of place at all. The colours work and I love it!
If you're like me and you plan on displaying it in robot mode only, the BIS Rodimus is a great alternative!
Sigh.. my Cyclonus on the other hand is flawed. For display purposes, cyclonus looks perfect in robot and alt modes. But soon as you being transforming, the hinge on the right arm for the black swing will pop out. It's happening because they used the wrong screw (a larger one). The larger screw causes the black plastic to bulge out so the swing arm won't fit securely. Someone else on TFW2005 reported the same issue.
