32mm GP5000 TL's are awesome.
I switched from tubed 28 GP5000s to these, and have been very happy. I wouldn't say the difference between them is dramatic, but the 32s definitely don't feel any slower and I can run them at lower pressure which makes for a more comfortable ride on rough stuff.
I'm around 165 and run my tubeless 32s at about 55-60psi on a 19mm internal rim.
