Paypal is terrible, but at least you can get on the phone and talk to someone when things get hairy. Every time I have google support issues I end up waiting days or weeks for automatic replies that don't even address the issue.
I've had nothing but excellent (less then 6 hour) response times from Stripe.
Got a 500 error back from their API once and had an email from one of their engineers in my inbox almost immediately after to find out what happened and resolve it (my http lib was using stale DNS).
If Google provides meaningful support for Wallet going forward, I hope they consider extending it to Apps - it's desperately needed.
that is not the general consensus of google apps customers, so i am curious what experiences have caused you to have this opinion.
