Why would that be preferable to Termux?
Because, wonderful as Termux is, it has a very nonstandard filesystem layout, so installation scripts for something like Anaconda will not run without extensive modifications. And Termux has no access to /proc, /dev etc., so lots of utilities fail. Since Terminal provides a full Linux VM, all programs that will run on Linux just work as expected.
I run htop just fine on my handhelds and I'm pretty sure it sources directly from /proc, /sys or something.
