There is a good review of vintage macro's in the 90 - 105 range here
Personally I've got the Vivitar Series 1 105/2.5 in Nikon Ai (hangover from D700 days). However, in the past I've compared it on a X-T1 with the Fuji 60 macro both at max aperture and I can only see a very slight difference in quality at 100% - The 60 is only very slightly sharper but its only 1:2 whereas the Viv is 1:1. Also the colour temp on the Viv renders a bit cooler.
I've kept it as the reviewer says it is a fantastic 'thing' the build quality and industrial design is superb.
