You posted this discussion back in July? I'll say Fabric still, I enjoy both but Fabric I enjoy more. I'd recommend putting Liteloader and Rift up there though for the 1.13, 1.12.2 and prior versions audience as they count for more and better results.
It's not just a 1.14+ thing with 2 modloaders after all. And more results works better, even if many will pick Forge because people know Forge more than the others.
