Not sure about reliability.

I know . But, I love Yamaha and I just really want a four stroke But with how much my carb has screwed me over, it makes me terrified to ride anything with a carb. I feel safe with efi

Carbs only screw you over if you never learn how to "fix" them.

I know how to disassemble, clean, and reassemble a carb. I just don't trust myself with working on carbs.

What could go wrong? It's not like you're trying to defuse a bomb here, it's just a carburetor

Well things could go wrong, like in the past I could grenade my rod bearing and have a 1200 dollar bill. I can't even get "in the zone" anymore because I am always scared that I am going to break something.
