I see your deluge and raise it to https://www.qbittorrent.org/
I'm a fan of client-daemon architecture, such as Tmux/Screen and IRC bouncers.
With that in mind I can recommend Tmux/Screen + rtorrent (daemon, ncurses) [1] + flood (WebUI) [2] for if you don't have CLI. Works well in Docker.
qBittorrent is the best for me feature wise. Also cross platform.
