I personally have only used Mount Baker Vapor as well, however I am not as impressed as others seem to be with it. Everything I have ordered was 24mg nic @ 65PG/35VG ratio. Now it may just be the fact that I am using inferior equipment and made a few bad flavor choices but it hasn't all been good.
MBV flavors I have tried:
555 - This smelled like waffles or maple syrup but tasted like sweaty socks to me...over time it got better, then worse again.
Watermelon +2 flavor shots - smelled great but tasted more like smoking watermelon scented dish soap.
Strawberry + 2 flavor shots - tasted faintly like Strawberry Quick milk mix this is what I still smoke mixed with menthol.
Sweet Cherry Bomb - not too bad, not a bad cherry flavor with mild undertones I couldn't quite make out.
MBV Menthol - this is a PURE clean Menthol, kind of strong for smoking straight but GREAT for mixing with other flavors.
Spearmint - kind of like the menthol this is a pure flavor, I like this one as a mixer as well, but prefer the menthol.
As mentioned I have inferior equipment...for now. This was all smoked using a cheap cig-a-like battery in Boge Cartos so better equipment or different /PG/VG ratios might yield better results than I had. Hope this helps.
Oh I do have better equipment coming in the mail and left overs of all flavors above except the Watermelon. I will retry them with the new setup and see if it changes anything.
