eSignal, MetaStock, or TradeStation?

I was wondering if anyone might be able to help me.

I have narrowed down my three potential software selections to eSignal, MetaStock, or TradeStation. They all appear to be similarly priced (on a monthly basis for the software at least)…

I have a few remaining questions that I was looking to find some answers for:

It appears that the MetaStock Pro QuoteCenter Subscription has the software and datafeeds bundled together, is this correct? If so, do either eSignal or TradeStation bundle the software and datafeeds in a similar fashion, or do you have to subscribe to individual datafeeds from the various exchanges?

If I am planning to be predominately a position trader, is real-time data necessary, or will end of day data suffice?

TradeStation has the added convenience of having an affiliated Broker, do eSignal and MetaStock have connectivity with Brokers, and, if so, which ones? This would affect where the assets for my trading account would be custodied.

Finally, as a general question, which one of these three software options do you find the best/would you go with?

Any insight anyone can provide me with will be very much appreciated. Thanks.

i have esignal and it is fantastic but pricey. For what you are doing Im not sure you need it
