This is one of those plugins that does something that you can't quite do in other ways. At least not without a bit of work.
Drum Leveler makes it super easy to level out real recorded drums, no matter if you want super even hits or just a bit of leveling out. I use it all the time for kick, snare, and toms, and it just does the job.
It does take some time to figure out the controls, but with a look in the manual you'll know what to do pretty quickly. Especially ghost notes can be tricky, but some experimenting will make it work, much thanks to the display where you can see exactly what's going on.
A pleasant surprise that I found was the gate. It's incredibly easy to use, especially compared to most other gates I've tried. Again, the display helps a lot (even though you're not usually meant to mix with your eyes hehe).
To be honest, I don't think anyone really need 20 different EQ's and 20 compressors, but this is a thing that you'll want to have if you're dealing with real recorded drums in a modern setting. I can happily recommend this plugin.
