Spread betting vs Forex Broker

Hello Guys

I am trying to find a new broker to place my forex trades with. I am currently with IG Index which have been perfect for what i need and haven't had any problems with, but they do not support MT4 trading which is the reason why i need to find another broker.

I have spent the weekend reading forum post after forum post on this and other forums but cant seem to find a broker which doesn't come with downsides, i know its all about finding a broker that suits my own personal needs but all this talk about adjusting spreads and freezing trades leaves me to think maybe i should forget the MT4 strategy and stick with IG Index.

I guess what i am asking is

Are spread betting firms more reliable and easier then other Forex brokers online.

I am looking to place trades from an AE automatically rather then placing them myself which i can do with IG Index

Thanks
