What kind of support would you be needing? It's an important question.
MetaQuotes has devoted a bit of energy to providing resources for developers and users up on the Internet and into their forums. There's a large community of users who practice "self-help" or community-help. However, if you run into a technical glitch with MT4, there isn't a number you can call up and have someone help you out. Most of the broker support people know less about MT4 than the typical MT4 trader.
So, the answer to your question depends on the type of support you need. What kinds of problems were you having with VT that caused you to want to switch?
