They're completely different. Both are evil, but Putin is extremely clever, which makes him a lot more dangerous than Trump. Trump can't do much more aside speaking to people bellies; surely he can amass lots of uneducated angry proud boys around him, but has zero credibility among the high ranks in the military.

Putin lives on a dream about making Russia great again by restoring the previous USSR borders. I'm not really sure he's as clever as you think.
