If I understand your question right you want to compare two campuses of BITS Pilani University, one BITS Pilani, Pilani Campus and BITS Pilani Goa Campus (also called KK Birla Goa Campus)
Well then bro you need to go into a bit detail like you need to mention criteria. Ive mentioned a few below:-
1. Placements :
Same everywhere in the BITS Pilani Universe. As in the companies go to every campus (at least in Pilani, Goa and Hyderabad), and there is no bias as such.
2. Education :
Depts. like Physics has awesome teachers at Goa, while CS has better faculty in Pilani, Hyderabad and Goa have nice Mech Engg. teachers, Finance faculty is nice in Hyderabad. So it solely depends on of the field/branch/dept. you are in (or at least interested in).
3. Campus :
All three are extremely beautiful. But Pilani campus is huge (almost 1000 acres),
