Based on the size of my bathroom, 100 cfm is fine but I would prefer something f more than that. All the contractors and vendors are saying don't do it. The only exception is my powder room because it's pretty small and 50 cfm is all it can do. I don't want to rip out the entire 3" piping for marginal gains.

I went with the 290 because
1) 90 wasn't enough since I found paint flaking on the door. I equated the flaking to moisture issues.
2) I had the clearance, it's a big beefy one, 9-10 inches depth.
3) I was able to easily run all new 6 inch duct
4) I grew up with noisy bathroom fans, so even though it's 2.0 sonnes, I'm still quiter than the one I replaced.
Perhaps your contractors are saying don't do it because they know how much harder it is to take out the old one and put in a new one since you potentially deal with cutting, drywall work and repainting. And the marginal gains if you kept the 3 inch. 4 and 6 inch was very common for the Panasonics that I looked up and some models come with adapters in the box.
I didn't mind all that work because I'm already doing drywall and paint work.
