Focus peaking, I think uses contrast. There are lenses with low contrast or low micro contrast that will be harder to use with focus peaking while others will just snap into focus and peak easily. The Mitakon may just be a lens that doesn't have much contrast at f/1.4 and thus focus peaking isn't the best.
AF. The 50s II should be faster, but I have never compared them. It will also have IBIS if you care for that. The AF even if faster will not be fast.
That site should be avoided, seems like simple AI full of errors. Contrary to what it says, the 50S with the EVF, battery, and memory card is a tiny bit heavier than the 50SII. Dimensions are similar except for the thickness due to the "big butt" of the 50S. Size wise, these to cameras could be considered about the same. Personally, I would take the nice built-in grip of the S or SII over the minor size and weight savings of the 50R but that's a personal choice. The major improvement of the SII, IMO, is the new style battery common to most other Fuji cameras and IBIS. They have the same AF. I had the 50S and really liked it. The AF didn't really bother me and I used the GF20-35 (doesn't really need stabe) and the GF45-100 which has its own stabilization. I didn't have any adapted lenses back then and didn't use manual focus much. Personally, I don't like MF much except on lenses that are fully manual. AF lenses don't seem to work well in MF mode, I can't explain why, that is simply my observation.
To me, coming from the 50S, the 50SII wasn't enough of an upgrade. I went to the 100S for very little differential cash. The 100S with better battery, IBIS, and AF, is noticeably better. IQ is essentially the same with additional crop-ability. The 100S just feels a little more coherent of a package to me, kind of all grown up. But they are all bargains and we are blessed with such choices.
