Neoq is new and we found it to have some features (like scheduling tasks) that were attractive. The maintainer has also been responsive to fixing our bug reports and addressing our concerns as we try it out.
Gue has been around for a while and is probably serving its users well.
Looking forward to trying out River now. I do wonder if neoq and river might be better off joining forces.
