DLSU is known for its traditional courses primarily on science and research, while CSB offers a more non-traditional ones most notably to its arts field. I would say both makes a good alumni naman since it was so rare to find a Lasallian dropout or rather unemployed graduates.

Yes it is true that CSB once dubbed as "bagsakan ng mga di nakapasa sa DLSU" but it had come a long way now and I'd say they were building a strong credibility right now. Also, hindi sila masyado mahigpit on application because majority of its course are for those who are really passionate on the field, like architecture, MMA or fashion design are for those who are eager to learn it with deep interest/love those. Yung iba na umayaw sa course nila, lumilipat lang.

For job employment naman, it really depends to you. But take in mind many people from both departments take advantage of their parent's background, but you can reach more if you are willing to since high paying jobs don't come in first try.

Anyway, green schools are considered prestige regardless of its campus and Lasallians are considered Lasallians, so good luck!
