I switched to zim years ago and found it has all the features that I need but is much faster and I think easier to install (though I haven’t installed either for some time).
Zimfw definitely has it's own ecosystem, plugins which are zimfw capable. But it's remarkably versatile at bringing in zsh code. Most plugin-systems are pretty ego-centric, demand specific implementations, and zimfw stands out not just for it's ridiculously impressive speed & handling, but for it's versatility too.
Zimfw rocks.
