I own a gen2 Glock 30. Have had it over 10 years now. My neighbor not long ago asked me to get his anti-gun wife educated on firearms topics, from ownership and safety to defensive use etc. in a matter of 2 months I got her to 180 from zero weapon tolerance to having to handguns in their house and constant range visits. She got a XDM9 and he got the XDS45. I've fired both a great deal of times. In comparison, I don't like the design in the Springfield frames. It's quite harsh for someone who shoots frequently. Very aggressive pattern that can, and will begin to chew your hand. Both the xd's and the G30 time must have a pinky grip extension, they are equal in that. The XDS has a very low capacity in comparison to the glock, though the XDM holds more. In terms of accuracy, I personally am far more proficient with the glock than either of the XD's. that's likely a combination of time spent shooting each, but again is related to the aggressive pattern on the XD frame. Glock has always to me been the pinnacle of simplicity and reliability. At the end of the day, shoot both models enough to learn your preference, and buy what suits you best.
A good plan executed today is better than a perfect plan executed at some indefinite point in the future.
