New Bottom Bracket

Hi everybody,
I need to get my bottom bracket replaced on my 2010 Specialized Stumpjumper Expert Carbon. I have taken it to my local store and they have ordered in for me the Shimano SM-BB71. Is this correct and would it work? From what I have read online many people suggest the BB91 that came with the bike. Which one would work the best? Have they got it wrong?
Here is the link to the original specification of the bike:

Many thanks in advance,
James

Both will fit, the SMBB91 is just a higher spec, and should last longer.0

Thanks for the quick reply. It's interesting that they have decided to replace it with a lower spec bb than was already in my bike. I presumed they would replace it with exactly the same part but when checking the receipt found otherwise. Aside from lasting longer is there any benefits performance wise? I may get them to change that.0

Perormance is the same - until it starts to wear ;-)0

Thanks for the help. Do you know roughly how many miles/km each one would be good for?0

Depends on conditions and how well the face is framed, hard to say really.0

Ok thanks. I am pretty OCD when it comes to kit so I think I will ask them to put the BB91 on instead of the BB71
