Every plugin manager I've used since Pathogen has seemed "triumphant" at the time. I think they've all been reliable enough and everytime I think well this will be the last time I change that.
I currently have a Packer config on one machine and Lazy on another and honestly don't know why I bothered switching to Lazy. What I really crave is simplicity so if NeoVim builds every thing in I think it will be good enough for me.
I switched from packer to lazy after I noticed the maintainer of packer stopped using packer in his neovim config. Also I believe he has now officially marked it as unmaintained and recommends lazy or pckr
