M4/3 to 1", now back to M4/3

A little story to tell. I've been into photography for quite a few years, I'm 67. I started the digital world with an Olympus E10 about 18 years ago. Only including DSLR's, I then went to Nikon starting with the D100, simply amazing at the time, and still not bad! I couldn't get enough, they had me hooked. D200, D300s, D7000, D7100, and lets not talk about lenses... Then came along M4/3. I think I started with a GX7, then E-M5 II and E-M1 II, and a lot of lenses. I sold all my Nikon gear. I still don't regret that move. But while I was enjoying M4/3 along came Sony with their 1" super zoom RX10 series. I thought, why not try one of these for travel, I picked up an RX10 III. It seemed wonderful, not much different than M4/3 and 24-600mm all-in-one. I started selling my M4/3 lenses that overlapped 24-600 and only keeping primes and Macro. I then moved to an RX10 IV with phase focus, again a great travel camera. My E-M1 II has mostly been sitting idle. I recently picked up my E-M1 II and shot a few photos. You know what, the E-M1 II really feels special to hold and use, much nicer quality wise and so much nice to use than the RX10's. I forgot just how nice the M4/3 format is. I'm very sorry I sold my 12-40, 12-100, 7-14, and 100-400. I'm starting to rebuild. I have an 8-18 showing up today (I tried one of these when they first came out in June 2017 and it was very soft in the left side, hope this one will be good). For a second lens I can't decide on 12-40 or 12-100, I liked them both.

Sorry this was so long, just revealing some of my mistakes.

I rotate my inventory at a much slower pace, so my unused gear accumulates.

Please comment more on your experience with RX10 III vs RX10 IV. Is the latter one noticeably better?
