It's probably a bit biased because I develop on Firefox/Chrome (very rare to find difference between the 2) and have to wait for reports/borrow an iOS device to test/debug. There might be similar issues with the aforementioned browsers, but the pain is less visible because it happens during development and I don't remember it. Also most of our users are using iOS devices, so reports for them are more likely. On the other my gut feeling is that iOS is more painful to develop for.
