Just making a comment as I found your wording here so clarifying for others how these work in Traktor.
"Traktor has separate Snap and Quantize buttons. Snap covers rounding (hot)cues and loops to beats and Quantize handles manipulation of playback."
Snap is for the settings of cue and loop points but doesn't affect playback in any way. Quantise is for playback, including keeping the triggering of hutcues or loops in time on the beat.
I've never found it an issue these being one and the same in Mixxx. Quantise is definitely useful to have separate for each deck though, especially if the music you are mixing is hard quantised/perfectly beatgrided mixed in with tracks where the tempo fluctuates and the grid is a only approximate.
