I have no experience with the yamaha, so, I'm pretty one sided, but, used to use the Honda eu1000 on our 21 foot boat, man that thing was quite....nothing like microwaving up a jimmy dean breakfast sandwich in the middle of the mothball fleet when your out fishing
it always started first or second pull, no matter what. I used to work at a small engine repair shop, and, you come to appreciated that fact, cause, a lot of older generators will take 10-15 pulls sometimes
