I'd go with the new 9mm. As far as reliability, it's just as reliable as the Glock except in -40F temps. It had a couple more malfunctions (out of 5000 rds). Otherwise is ran neck and neck with the Glock.
This was from the full size tests, but both the sub-compact pistols from Glock and Springfield are just as reliable as their big brothers.
