Moon Knight (Marc Spector) vs Captain America (Steve Rogers)

Moon Knight from the new Disney+ show takes on Steve Rogers from the MCU.

Round 1: Marc Spector vs Steve Rogers (No suits)

Round 2: Moon Knight vs Captain America (Both in their suits, Marc doesn't have his throwing weapons, Cap doesn't have his shield)

Round 3: Moon Knight vs Captain America (Both have their equipment)

Victory by death or KO, who wins?

Cap in first two. Moon Knight in 3.

Round 1: Cap stomps
Round 2: Cap puts up a fight but Moon Knight's suit will keep healing him. MK wins.
Round 3: Toss up. With the shield Cap might be able to injure MK enough to KO him but MK's weapons will obviously mess up Cap if it hits.

Cap probably via incap
Spector beats him down
Not seeing how Cap wins given the regen/incredible durability (he was literally tanking an IG blast equivalent (Ammit was stealing peoples souls) and he was tanking those staff blasts with his bare arms. Spector probably just outlasts him
