I have two RICs, a 4001 and a 4003. I also have three P-Basses. I grew up, music wise, 50 years ago. So ergonomics were not even a thought. You just adapted and adjusted to your bass. Never had a problem with any of my basses, and the 4001 and my 78 P-bass were abused in the day. Still, I enjoy all my basses. Do I have a preference, nope. I just pick up one that suits the song I want to play. And yes, even though it's a stereotype, I have flats on my P-basses and RotoSounds on my RICs. If you have the money and are GAS'ing for a certain bass, buy it.
