Photography

I'm torn about selling my EF glass, since I'm mostly shooting on an RF body along with some M 4/3 gear. I still have an old 5D classic, which I'm gifting to my 13 y/o nephew but I also have a 24-105L, an EF 50 1.4 and a Tamron 17-35. I've already sold the EF 100-400 and 70-200, as it was just too bulky for me to manage.
I often run across videos extolling the virtues of buying a 6D classic, or similar. The wonderful color and film like quality. I'm hard pressed to say I see that in my modern R8 while shooting landscapes, travel and family shots. So on one hand, I'm lusting for that kind of look in my own pics and my latest bout of GAS has me already looking for 6D deals.

But on the other hand:
I feel like there are too many gear choices on my shelf, and maybe I'd improve my photography more by going deeper with less gear. Would love to hear your thoughts and experiences along these lines.
