Neither of these shidduch systems are perfect. However, here are some thoughts:
1. As a chassidish girl, I know exactly how much time and energy is put into getting information on the other party before a beshow is arranged. But people lie through their teeth when it comes to shidduchim. I’ve seen hearing people go deaf and seeing people go blind when they’re asked information about someone who they’d rather not talk about.
2. Unless a girl/boy is mature enough to know what it is s/he’s trying to get out of the dating process, it’s one big waste of time. Spending hours enxchanging funny yeshiva/sem/camp experiences does NOT count for getting to know the other person for real. It’s a pity that immature daters get the same amount of real talk done in all their dates put together, as a chassidish couple can do in 2-4 beshows.
3. Date or beshow, you only truly know the person once you’re married.
