Not sure if comparable, but I have an '04 150 vmax (carbed). It has been great in almost 4 years of ownership so far. Recently, I did the worst thing for an outboard that you can do --- let it sit for an extended period of time --- and had to clean the carbs, impeller, stats and poppet valve. Now it's like back to excellent running form. I was skeptical at switching from Mercury to Yamaha, but I have to say it's been fine. I think they are pretty reliable motors. As long as you keep them serviced, they should be fine. And of course, as a mechanic reminded me years ago, don't let them sit for too long because they are made to be run.
