The Leica is probably the best feeling medium format to use. They really nailed the body. The lenses are sweet too, as usual. However...it is 3:2 format and has a mirror. Both of which kept me away. Honestly mirrorless won me over, and it’s hard to go back. I still use an H system on occasion and it reminds me every time why mirrorless is the future. Also, I really prefer 4:3 ratio for architecture. A little. Extra ceiling can go a long way in feeling more natural, at least to me.
