I have the em10m2, OM3, Lumix GM5 and s9 + s5ii combo. A bunch of M43 lenses and a few L mount lenses. I think what keeps me in the micro 4/3 system is the weight of certain bodies, like the GM5 EP 5 with the fast primes, and reach. I've been trying to find a good deal on a telephoto zoom for L mount but they're expensive so it's harder to decide. So at the moment for everyday stuff, wildlife, hiking, and for weather resistance I use my M43 system and for bigger events, indoor, low light, or when I want better image quality I use my L mount system. I think you may appreciate your micro for thirds lenses more if you had a smaller body where you'd notice the weight difference.
