Get the one you love more!!!
My first watch was 36 but back then big watches were much more popular.
I also have a 31 and 28, and mostly wear 28 now. I still love my 36 and 31 but haven’t worn them in years. Actually now thinking about it I’m feeling guilty to my beautiful watches lol. Need to wear the 36 tomorrow!
For reference I’m 5.11 (180sm), my wrists are about 14 sm, Cartier love size 16.
