I'm always conscious of not going on about this too much, for fear of boring everyone - but the most fun I've had from my photography in the last couple of years has been with my 10MP Samsung GX-10 (two of them, actually), and - to a lesser extent (and only then because of less use) - my Samsung GX-1L and Pentax *ist DL. After that, I'd say the Q-7 has been immensely good fun too.
As for lenses, I've become thoroughly ambivalent about razor-edge sharpness at 100% reproduction, and I'm far more interested in overall rendering. I've got some nice, modern, sharp lenses, some of which also render very nicely... but I'm happiest with my humble Tamron 28-75 f/2.8. And it's amazing what GBP £30 - £50 can buy in terms of vintage, manual lenses with absolutely beautiful and/or quirky rendering.
I like all of my kit, and I'm fortunate to have a fair amount of stuff to choose from, but if I had to give it all up tomorrow and keep just one of my GX-10s and the Tamron, that would suit me just fine. Plus, maybe, a couple of those old manual lenses, just to add a bit of variety
Like you, I've become more and more kit aware... but I'm less bothered about it now than I ever was.
