eshell:

  Welcome to the Emacs shell
  ~ $ btop
  ERROR: Failed to get size of terminal!
  ~ [1] $

shell:

  $ btop                                                           
  Terminal size too small: Width = 79 Height = 22Needed for current config:Width = 80 Height = 24

If I increase the width and height, I get an extremely weird output.

Same as shell.

Any other Emacs shells I missed?

In any case, I do not use any shells within Emacs. I use XTerm separately.

Visual programs won't work within emacs standard shell interaction. Only line oriented programs works (printing one line at a time and exiting). But for many visual programs, you have the equivalent in Emacs.

For interactive stuff you probably want eat https://github.com/kephale/emacs-eat or vterm

(I don't use them, I prefer my shells to last even if I should restart emacs)

Don't say that too loud or the "you should never have to restart Emacs" folks might hear you!

libvterm https://github.com/akermu/emacs-libvterm

M-x vterm

Does it have to be the GUI version of Emacs?

No. Vterm works fine even in a terminal version of emacs.
