Chandigarh University or Chandigarh group of colleges for BCA
You can go for Chandigarh University itself since it has good placements and also the colleges are well designed with good infrastructure and a decent teaching and non teaching staff, cool facilities and great faculty.
So on that basis you can prefer it over Chandigarh group of colleges.
