Depends on what you want to do with them. I personally like the STI in widebody, and the EVo is nice widebodied too. (Have YET to see the MSP in widebody form) Notice the YET
Anyways, it all depends on what direction YOU want to take. For stock appearance, the Evo is nice, and follows the MSp body lines a bit. The STI is more rounded off, but is still nice.
