Given that Chrome and Safari use webkit has anyone yet found anything that renders differently on Chrome than Safari? Is there any reason at the moment to test sites on both, o
No. This would be a similar question to "Does Chrome Render the same as Konqueror", and altho the Webkit ( HTML Renderer ) versions may be different, the Java script engines are very different between Chrome, Safari and Konqueror. This will affect a lot of Google apps since they are written using javascript heavy stuff (AJAX). This also seems to affect a lot of modern sites, especially ones with complex menu's and editors ( such as this ). In the end it depends how much of the site you are viewing is written with javascript features.
