I haven’t ever tried it so unfortunately I can’t directly compare. I’ve been using kodi + debrid for years though with zero issues, and since it served my needs perfectly I haven’t tried anything new since. I even set it up on a chromecast for my tech illiterate dad, and he’s been cable/stream service free since.
You need to install extensions before you can use the source section to perform a search. Once you’ve done that, typing something into the search field under sources will search through all the extensions you have installed.
They have an entire guide on that.
