I think it depends on the specific schools as some MT degrees are also BM degrees with a music focus. But I would say at most schools the area you would get the least training as a VP instead of MT is dance. So you may want to ask yourself what kind of dance training you want and can you get that in the programs you are considering.
Also, be careful. Not all MT programs are acting first. Make sure you really examine the degree requirements and make sure those are classes you want to take.
You also may want to determine how VPs and MTs work on the same campus, for example, at OCU, VPS and MTs share voice studios and all audition for and are cast in both operas and musicals. I believe at Baldwin Wallace, the VP program is totally independent of the MT program and it is more rare to find them in the same classes or shows. (But please confirm this with someone from Baldwin Wallace. We have friends there in both programs who both love it. But they are not in the same classes or shows so that is our only personal experience at BW).
Lastly, see if you can find out how VPs and MTs spend their summers? And where are they working after graduation? D had a friend from OCU who graduated as a VP and her first job just weeks after graduating was the lead in the national tour of Jekyll and Hyde. but I believe her next role is with an opera company. So it is possible to do both if you are right for the roles. But the contact you need are different for each.
Lastly, examine your heart. Which will make you happy? Which school fits you best in addition to the program? Trust your gut. Best wishes to you in picking the perfect program for you!
