Having trained both in a university and 'club' flying school, the difference between the two (airline standard flying training) is really very minor and is a bit of a glitzy word. At the end of the day, I got great and average training at both, the difference being the quality of the instructor and our interaction.
At the end of the day, it's the instructor who makes the most difference in my opinion and I have been lucky enough to have some great ones!
