A spot that I struggle with

[45suited]

Does anyone else struggle in these spots? I'm in comfortable chip position, a shortish UTG goes all-in. I'm confident that I've probably got the better hand. Sure, he could have a pair but UTG's in his chip position also push alot of weak aces, kings, etc. (He's also been pretty LAG.) Is it worth risking half my stack from the SB here? FWIW, I called, but I'm curious as to the thought process of some other people here.
