Would PB offer a better quoting/news feed? https://www.wedbush.com/services/ct/prime-brokerage http://www.limebrokerage.com/
Compared to a retail brokerage? Yes, for most retail houses. IB is more geared for a professional and is pretty good for a retail broker, but it doesn't have everything like an Eikon/Bloomberg terminal would have. Keep in mind, professional data feeds are not cheap. You don't get them free like a TDameritrade. Now if you're asking about individual platform offerings, I wouldn't know. I connect my accounts into my Eikon terminal. Robert Morse might know more about what you're asking.
