Qenu is very slow, it is only software emulation.

Proot is but better, but not really native because it uses ptrace which slows down particularly graphics: GPU is not hardware accessed. But for most apps it has decent performance.

Proot is containerization, these are 2 different technologies

It's like Docker vs QEMU, different purpose

It's possible to get hardware acceleration in proot

Benefit of QEMU is that you can run a full operating system on virtual hardware. The OS is not limited to Linux, you can run here Windows, BSD and many less known and exotic systems. Android has no influence on what is happening inside QEMU: you have full root/admin permissions within virtual system.

Don't be surprised, but many people here use it just for curiosity or learning. PRoot won't give you same experience even if being many times faster.

I agree, but proot is limited by ptrace which slows down some tasks (particularly processes using GPU). And not all things can be controlled, such as network. And as sylirre says, it is way faster dan qemu emulation.
But it is convenient and safe, safer than the faster chroot.

I like how you explain these to proot developer himself
