Why native
Has more competitive players than NW, has support from TW, is primary combat system of the franchise that will be used in Bannerlord, has more skills to master (even incredible mechanical players can be wack in battle with archers and cav involved), you can play more than just melee-only modes, you can play melee-only modes if you want too with group fighting and duels, 4 directions instead of 2, player and team legacies going back to 2010 etc.
For me personally, I was a full invasion 2 player so Native made most sense for me to switch to.
