Mint is a goto debian distro, but I switched from Debian unstable to mint and my experience is worse.
PulseAudio is wierd, when suspensing last 1 sec of audio loops, crashes,
Mint is based on testing irc.
I switched to unstable because I wanted the latest kernel and latest Plasma, my experience has been mostly positive but there are weird issues like not being able to install ffmpeg due to some dependency conflict. I can compile ffmpeg from source and install just fine tho
