depends on what you are trying to do/want?
at this point, other than the canon & nikon mirrorless, every system has a good library of lenses...though i do think fuji's lenses/system have a particular appeal for some
with many of their previous generation cameras, it used to be true that fuji sensors were designed differently (i forget the particulars but their sensors read color differently that traditional sensors, #doyourgoogles if you want the specifics), but this also caused some difficulties with post-processors, now they basically use the same sensors as every one else but put their own color science on top of it...
this is definitely one of the strengths of the sony system...while it is technically possible for all mirrorless to adapt lenses, because of the enthusiasm around all the capabilities packed into sony cameras, there is much more development going on to adapt other lenses specifically to sony cameras
which pizza joint did you hit and how did you like the go? for the pics it's a very minor ting and usually easily correctable, but look out for the color fringing on the right side of these magenta on the 1st, green on the 2nd...
