I don't know which ones you've tried, but the most popular ones (Magnet and Rectangle) have worked perfectly for me for years. I routinely forget that I have Rectangle installed.
I've been happy with Divvy for many years. It's not autotiling but the one-time config setup is intuitive after which my kbd shortcuts put things exactly where I want em, so I hardly ever think about it.
I have to use XQuartz for some apps I run in macOS. Magnet (and other apps I've tried) don't understand those windows. ShiftIt does, but it's buggy and no longer maintained.
