The 190 has significantly bigger main landing gear wheels and brakes than the 170. Flying both types side-by-side, off the same limiting runway close to MTOW for each type, the 190 is usually far less limiting. There have been many times off short and obstacle limited runways I’ve wished I was in a 190 and not a 170... never the other way around.
As for system differences, E90/195 also has a Mach Trim system that the E170/175 do not.
