Lol yeah even my smaller Xr feels like a brick. I did not have wrist strain when I had the Max so the weight didn't bother me at the time.
What I like about my S10+ so far is how extensively customized I have it. I absolutely love my calendar widget and the fact I have it exactly one slide over from my home page and have other smaller useful widgets with it, all arranged exactly as I want them. I can also customize my 3XL and I have. But the OneUI takes customization to another level.
I also enjoy being back on Samsung mail and I like having both Samsung Gallery and Google photos. I know that drives some people crazy but I like having both available to me.
I am also liking the stock keyboard for this forum. Usually I prefer Gboard, but Gboard and my iPhone keyboard have struggled to get along with this forum's text entry interface. On my iPhone text selection has been messed up. And on GBoard on my Pixel text correction has been weird and ridiculous. Everything "just works" on my S10+
