BrainVoyager's approaches are from the ice age and not flexible enough to handle modern protocols. Only a moron could defend using it for research. It's tranlational at best (a toy you give those clinicians that can't even figure out SPM). But it does make pretty pictures.
I'm a clinician and it admittedly took me ages to figure out SPM. I still hate it, and think it is terrible to work with but useful. The state of the software is actively hampering contributions from clinicians. The problem is, as you have pointed out, that if BrainVoyager is the alternative, that's no alternative at all.
