We just put Pirelli Scorpions on my wife's 2017 RX350. They seem to be doing real well for her. I don't drive it much myself so I can't give too much of an opinion.
At the risk of starting the pissing contest you mentioned, I have the Terra Grapplers on my 2019 ORP and have found them to be very competent in rain. We were on a road trip in January in West Texas and were driving 70 miles an hour in heavy rain for hours with no hydroplaning or otherwise feeling not secure on the road. I'm a pretty conservative driver so I slow down for tight curves and that sort of thing. Anyway YMMV.
