I use G1, and I think it's actually the default now for newer Cassandra versions. For G1, I've done very little custom config/tuning. I increased heap to 16GB (out of 64GB physical), but most of the rest is at or near default. For the most part, it's been "feed it more RAM, and it works" compared to CMS's "lower overhead, works great until it doesn't" and dozens of knobs.
I haven't tried ZGC yet, but anecdotally I've heard that it doesn't really match or beat G1 quite yet.
