I would say +1 for map units.

Regarding Marco’s use case, using the 50cm limit should be equivalent in map units, no?

From my point of view, the settings of snapping are far too advanced for 95% of the usage. Let’s not make them even more complicated, just for a very specific use case.

My 2 ct.

Recently there was even a bug report filed for that: https://hub.qgis.org/issues/11634 <https://hub.qgis.org/issues/11634>
