Welcome to the forum, Joe.
I had it done a couple of years ago - RT & HT is a bit of a long drawn out thing, but it worked for me. HT will just about kill any sex urge whilst your on it, but it does return eventually. At least no calving up or General anaesthetic involved.
It's worked for me with minimal side effects. My PSA was 27 in 2018 - I suspect if I had not had it done, I would not be typing this message to you now.
It's a bleak choice.
