Sig sauer compared to Glock?

I'm considering buying either a Sig sauer p250 or a Glock g19 or g23. I've received mixed reviews between the sigs and glocks, I've heard that glocks last longer but are less accurate than a sig. Im leaning towards the p250 because of the interchangeable rounds option. (I would probably end up shooting mostly 9mm though) any owners of both that have any advise?
