Cheaper? Yes. More dependable? I doubt it.

I think I would use the holley terminator if I were going to go with a TBI/EFI deal in place of the carb, because it can be manually tuned later if you feel the need to.

If you have the wiring/electrical knowledge/cash, I still think you're best served by a multi-port setup with a standalone. Something like MS3 or a holley dominator efi.

I'm running multi-port efi with the MS3 Pro. Once you get it set up, do a bit of tuning, it's amazing. The car runs amazingly smooth.
