Seems like people like to pick on PayPal because they want to see the new 'startups' win. But PayPal doesn't have to lose for them to win.
To expand. We thought about switching to Stripe once. Implementation was fairly annoying compared to PayPal's which was surprising considering how loved they are by the dev community. Their fees were much higher. Support couldn't answer some relatively easy questions. Stupid turnaround time for bank deposits.
I can understand how getting setup with a Stripe branded payment form is easy and saves some hassle for a new project. But as an established business they don't bring much to the table. We passed and skipped the obligatory 'X Sucks Because Y' article.
