It is often seen in major Star Wars space battles that rebel fleets, containing Mon Calamari star cruisers, fight Imperial star destroyers. However, its appears (from my perception) that both can be (relatively) easily destroyed by other smaller star fighters, such as X-Wings or TIE fighters (or at least depicted in Star Wars Rebels and at the Battle of Endor.)
My question is this: Which would win between a Mon Calamari star cruiser and an Imperial Star Destroyer, taking into account if it was a single ship-on-ship battle? For the sake of adding detail, I am specifying that the Mon Calamari star cruiser would be a MC80 star cruiser and the Imperial Star Destroyer would be a Imperial II-class Star Destroyer.
