It’s mostly that it’s just an older site and the voting/review system goes back by over a decade. Much of the information you’re gonna get on there is just dated, pure and simple, and that reflects in the rankings.

And as you said, the categories aren’t curated well enough. Too many unrelated suggestions.

Only issue with alternativeto is the comments and reviews are all dated, some by over 10 years, and often don’t reflect the current state of the software.

A lot of the information on the site just feels very stale in general.
