I don't rate Safari at all. No favicons, can't block video ads, limited extensions, always behind the times (pinned tabs 5 years after Chrome), not cross-platform, no Chromecast support, can only restore one tab with cmd+z and no recent tabs, updates only once a year, need to have flash installed to see flash content, occasional stutters and beachballs, have to install an extension to get a reload button...
Now that the Chrome team are taking battery life seriously (it's literally improving every month) I see no reason to use Safari unless you are firmly in Apple's ecosystem. Whoever it is at Apple who is preventing favicons in Safari is a total nob. At least make it a preference or even a Terminal command for those who want it you utter pillocks.
