I think going from Halo to MBV will be disappointing. Just my 2 cents.
You should check out Good Life Vapor.
To provide an alternate argument, my first vendor was Halo. My next was MBV. That was over 2 months ago, and I've ordered from them quite a few times, and have had zero interest in revisiting Halo.
When you first start out, you'll have no idea what you might like until you find some stuff you do like. This totally makes the early days frustrating sometimes.
MBV does a good, more natural than candy, Coconut. I really enjoy their Key Lime, and Pink Lemonade is frequently hyped up. Double Apple is also very popular.
As for tobaccos, I will say right out that Tobacco flavors seem to be MBV's weakest area. That said, the ones I've heard good things about include East Coast Tobacco and Coumarin Pipe. However, expect to wait about a month from the day they ship until they're really enjoyable - they tend to need a long steep (longer if you order larger bottles).
