Application Selection Advice

I have a slight predicament.
2 of the colleges I’m apply to accept only Common, 1 of them accepts only Coalition, and all the rest accept either. I identify more with the Coalition essay prompts, but my college counselor at my school seems to prefer Common app (and I can’t currently ask her).
Any ideas which portal I should use for the 5 colleges that don’t have a preference?
Not applying to the college that only accepts Coalition is not an option.

If you prefer the Coalition application, then use that one. I work for admissions at Northeastern University and we accept both the Coalition and Common application and the admissions counselors really do not care which one you use. If they offer both then it doesn’t matter which one to use.
