I like the older cameras. I first shot an Olympus E1 until the sensor died and by that time Olympus wasn't doing any more service on the camera. So I got a secondhand 5D and shot that for 4 years, mainly with a 50mm Summicron-R in black and white, which had great texture and that Leica "feel" to the images. For colour I used the lowly 50mm 1.8 but found it was more than good enough for the people shots I used it for. Sometimes an 85mm 1.8 for street and portraits, but I sold it off when I discovered I didn't really like auto focus; it seemed like cheating.
I finally sold off the 5D after I got an ultra- cheap, used Fuji S5 Pro and buyer's guilt made it unable to justify having two DSLRs at one time. Plus I get confused about battery chargers. I still shoot with the Fuji, mainly with 40mm and 58mm Voigtlanders, and now with a 90mm Tamron Macro. I have seen images from a friend's Fuji X100T but I think there's something to the S5 Pro results that make the older tech better to my eyes.
And I think that's really the thing: shoot whatever makes great results to your eyes.
For digital, I also have the Sony A5100, bought mainly for video, don't like the output for photos. I have the Ricoh GXR, too, and I prefer its output better for photos, plus it feels like a camera whereas the Sony is like a box of electronics. The Sony takes higher res, sharper photos. But it's the GXR (with a Leica CL) that I carry with me all the time.
