Who has an easier first round

Editorial comparison: Murder Mystery 2 has a decade of guides and a trading layer you can ignore. Moo Moo Mystery’s extra rule is the shapeshift, which is also the main tell. MM2 explicitly advertises knife trading; the checked Moo Moo Mystery description does not document the same feature. If a Moderate violence label is a problem, Murder Mystery 2’s label is the stricter of the two official labels in this snapshot.

What I checked

Official descriptions supply the role names and MM2 knife-trading feature. The table uses creation dates, not demonstrated release dates. Pace and learning difficulty are editorial considerations, not measured round times. All Roblox fields belong to one publisher; the 01:44 UTC counters are historical snapshots.
