I'm taking about a Glock 26 vs something like an XDS.11 vs 6 is a good argument, you'll get no fight from me on that. That isn't always the case though. 11 in a gun that maxes out at 11 vs 11 in a gun that can have 18 with a normal mag is less compelling.
My 26 can actually max out at 14 with an extension. It can even accept a 33 rounder. A 19 with a 10 round magazine can accept a 17 rd magazine compared to a Glock of the. 45 flavor that'll max out at about 13.
