In most cases I prefer the standard gnome stuff (browser is the big exception).

Web Browser: Chromium / Firefox / Epiphany Email Client: Evolution / Mutt / Thunderbird Terminal: gnome-terminal File manager: nautilus Text editor: gedit IRC: weechat / polaris Office Suite: google docs / libreoffice Calendar: google calendar / gnome calendar Video Player: Totem / mpv Photo Viewer: Shotwell (I wish gnome-photos would work but its reliance on Tracker makes it unusable for me (what is with tracker not following symlinks?? please fix that). Screen recording: I wish the gnome-builtin one did sound, since it doesn't I use SimpleScreenRecorder)
