I'm curious to comparison and input, too!
I have actually played both, but would like others' input as well.
I thought both played very well. Yamaha is a good price/value. Tone knob has wide range of sounds, along with both pickips. Godin fit and finish were amazing. Slightly thinner neck - like a jazz. Amazing neck. I only played two Godin shifter classes that were used at Guitar center - they played well, but I thought the electronics were loud and boomy - both - I don't know if that is normal, or if they just needed a set up. I asked that question in a Godin thread a few months ago, and never got a response.
Based on my experience, I thought Yamaha sounded better, but Godin had better fit/finish and playability. If I could try a new, pro set up Godin and it sounded better than my experience above, then I would pick the Godin.
