Do people have opinions about bike locks? Like, which ones are better than others, and why?

Context:
Last Monday I biked home from a rehearsal held near MIT. Somewhere along the darkened paths of Memorial Drive I lost my keyring.

Not the usb drive and key chain on my key chain, just the ring with my keys on it. If I'm being honest this is more of an annoyance than anything else. There were only four keys on the ring in the first place, two of which were to bike locks, and one of the others went to a lock that's since been changed. The last key, well...there are spares.

But now I find myself in need of a new bike lock, and I'm trying to figure out which way I should go:
- Another U-lock - An actual chain and pad lock? - Combination of both?

Tell me your thoughts about bike locks, because...I've got nothing here.
