Most of the sessions I do are recorded direct because it's the quickest to set up, and that's important when you have 30 minutes to track bass. A good direct box like a JDI will give you a workable clean sound that can be easily sculpted to fit the track during mixing. Now that I've been using a REDDI, I have no qualms about showing up to a session ampless.
But when I'm tracking bass at my place for someone, I always record through an amp or reamp. A good tube amp does things to the bass signal that can't be emulated with a Distressor, and 9 times out of 10 only the amp track is used. One of the best bass tones I've ever recorded was an old SVT through an Epifani 112 cab.
If miking an amp isn't an option, there are some plugins out there that sound pretty good. The Amplitube stuff isn't bad, and Avid just modeled a 1969 SVT for the expansion to their Eleven plugin that I'm dying to try.
