Bad rotations would be where you let just about anyone create and abandon rotations halfassed. starts with P, ends with S.
If you want something internal then its either nilname or daemonic for windows, Lunar for MacOS. but since price is part of the question i suggest nilname advanced plus, 30 bucks and you get rotations that slap on every class included in that. lunar is also good rotation wise and works with nilname but is an extra cost of like 60 bucks on top of nilnames cost so that would take you over the 20+50 spending youre doing at PS+murlok i presume.. theres also ascended rotations which is a new framework that looks promising and offers a free trial, you do need nilname to use it though.
as For pixels my recommendation is idk i havent used the public pixels
