It's not an angle. It's a measurement in mm.
There is not much difference in the major brands which fall in the 145 - 150 mm range. See here http://weightweenies.starbike.com/forum/viewtopic.php?t=63682
I had the SRAM specs once but cannot find now. Their BB30 and GXP cranks had the same Q-factor.

There's sometimes a buggy.
How many drivers does a buggy have?
One.
So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.

If I'm not mistaken, it's 149.2mm for the GXP version and 145mm for BB30. The newer GXP cranks have a Q-factor of 145.3mm

Maybe. Backup?
There is no inherent reason why a BB30 crank would be any different than a GXP crank when it comes to Q factor.
Here's one example from SRAM
