I still have my Nikon RF , 35 , 50 and 105 but dont use them
I regret selling all my Leica lenses
But dont regret selling the m3 , m4 and m6
For me I like the ability to switch to monochrome to color simply
I like to see my aperature and shutter speed and change it without going to a menu
To quickly change my iso
I like that I can use any brand of lens with an adapter
I like the weight of my XE-2 but felt my Pro-1 was heavy
I like that i can check the shot right away and not wait a week
I like the focus peaking of the newer Fuji's , much easier to focus
When using a 50mm lens I can keep both eyes open because the viewfinder shows exactly , i think that is for the XE-2 and Pro1-2. The xt-1 and xt-2 are set for 35mm
I like that the xe and pro finder is on the left and not in the center, my nose mushes up against the screen
I would recommend getting a xe2 and use your Leica lenses with a $20 adapter for each lens
The 35 and 50 are my favorite
