I've played both and had a P35. The 435 was a great bass, no doubt. The BBP35 was an amazing bass. Just rock solid. I sold because it was heavier than what I wanted to deal with. But the feel, sound and especially the B string were just amazing. You could put a custom builders name on there and charge another $1000. Seriously amazing bass. Yes expensive compared to Yamahas lower price options, but a bargain if you compare it to basses of similar quality.
