Content: variety versus specialisation
Competizione lives around one category and its circuits. That has an underappreciated advantage: when every car belongs to the same family, racing is very close and learning one transfers to the rest.
EVO mixes modern road cars, classics, sports cars and very different racing machinery. You go from eighties hatchbacks to current GT3s by way of single-seaters. Learning them doesn't transfer the same way: a classic without aids and a GT3 with aero don't drive remotely alike.
Practical consequence: if you get bored lapping the same thing, EVO's variety is welcome. If what you want is to master one category thoroughly, specialisation works in your favour.
