I did not have your experience and judging by the ratings in the App store neither did many others.
App Store - Perfect Browser - EXTRAORDINARY Fullscreen Browser
Perhaps you tried an old version and not a new one. I need glasses and I find the inability of Safari to text re-flow very annoying. Anyway, different strokes to different folks
I have been using Chrome since it was released, and I really like how it's tied in with my desktop. It's my go-to browser now.
Chrome is a great alternative but it doesn't offer the integrated features or extra speed boost that Safari provides. I'll be sticking with Safari and I think most people will, especially as the integration across iCloud goes deeper.
