I have 32mm GP5K tubeless and 25mm Pro One 2016s but on different bikes, so difficult to make comparisons. I've not punctured with either in the past year and a half that I've run tubeless. I'm lighter than OP, enjoy running lower pressure, definitely had punctures and pinch-flats in the past when running tubes so there's no way I'm going backwards to tubed.
The GP5Ks are consistently tested to be the fastest practical (non-TT) tire to run if you don't want to faff around with latex tubes, and anecdotally people seem to have good luck with how long they last compared to all generations of Pro Ones, so if you want to try them out, go for it. The only issue is that GP5Ks are a big no for hookless rims.
