I just avoided HEVC but I ultimately stopped using an RP3 as a TV because of audio timing issues that became apparent with Dolby Atmos. I now use a Odroid N2+, which I recommend.
I'm pretty sure I've used a RPi 2 for HD content too but that did suck. The UI was a little laggy and I had to manually set NFS mounts because even SMB caused too much overhead. Once the stream started it played most content ok but god help you if you needed to fast forward or rewind.
My exact question too. Anybody care to help us out?

h.265 provides identical quality at smaller file size—much, much smaller file size, for some content (animation) but it's still a fair improvement for most other cases.
