Well, if you are going to compare specific positions you are already wrong, since it would be:
Duelist: Aspas </=/> Mwzera (Both play the role of duelist very well, but obviously MW has a better Raze and impact, but that can be debatable since Aspas flexibility is greater)
Flex: Saadhak =/> Murizzz (Saadhak as igl is better and smarter, but in aim Murizzz is better)
Initiator: Sacy >>>>>>> Rhz (I don't even need to say anything here, it's the bald man)
Chamber: Less <<<< Heat (Chamber basically became the fixed sentinel of the teams, so if you put in that category only Chamber, Heat just destroys, aims better, more impact, Operator better, etc. If considering general Sentry that is not the current meta, Less has an advantage for flexibility.
Smokes: Pancada=/>> RglMeister: Both are extremely smart and incredibly good at clutching, Rgl has a better tactical game than Pancada, but Pancada has one of the best aim on the server if not the best.
But well, it's my opinion, Loud's main difference is not players, but the set of everything that makes up the game
