Interactive Brokers Data Question

Does anyone know the functional difference of the following data sets for ES futures only via Interactive Brokers?

There's a fee difference but no functional difference as far as I can tell:

• US Futures Value Bundle PLUS
  
• CME Real-Time

 

CME Real-Time is generally for those with professional user status. If not a professional, use the Value Bundle PLUS and save as it has L2 data and and market depth for CBOT, CME, COMEX and NYMEX.

 

Thanks. Are the two data sets are identical for CME futures? Or are there minor differences?

 

I believe they are the same and just another way for exchanges to maximize their lust for gauging anyone who has a license or is a non-person regardless of how much they trade.
