That's a tough one to decide on.
I love them both, and I agree with you completely.
Boogie Nights is far more entertaining. However, Magnolia is deep and gripping. Both have excellent ensemble cast performances. The strongest performance of them all has got to be Tom Cruise in Magnolia when he cries frantically over his estranged and ailing father. It gets to me all the time.
If I had to choose one over the other...I'd pick Magnolia.
