According to the Team Liquid wiki:
Marauders are weak to marines.
Let's think about this a little:
Marauders do 10 damage to marines and have almost twice the cooldown... so in 'normal condition' or under stim-pack they do similar damage to each other. Marines have 45 HP (55 with upgrade) instead of 125 and costs 50 + 12.5 supply = 62.5 instead of 100 + 25 supply + 25 gas = 150.
If we take mineral/gas cost into account, the amount of marines will be usually 2.5 bigger than marauders (X marauders against 2.5X marines), with approximately similar amount of HP to kill each group.
The difference I see is concussive shells.
X marauders can constantly 'slow down' X marines, and slowed marines will do half as much damage. So 'actually', if we consider DPS we will have X marauders against 2X marines, which is significantly more(turns out this information was wrong).
Could you please clarify why Team Liquid consider marauders weak against marines?
