A few comments.

If your experience go back to OS 9 and earlier, a lot of BIAB for the Mac makes perfect sense. Will that Preference layout survive into 64 bit? I hope not for those who started on Macs in the 21st C. — but I'm quite comfortable with it.

There's a 64 bit version coming. It's been released for Windows already and the next Mac OS will require it. If not in a hurry, you might wait till then.

You do not say what your current Mac is nor what version of BIAB you are running — it definitely can make a difference.

Even more so than the version, how you have it installed can have a great effect.
