- bookmarks feature
- home screen with commonly visited pages
- speed, it's a very fast browser
- reliable because it rarely crashes, perhaps even more reliable than Google Chrome
- good notification prompts, blocks pop-ups by default
- doesn't require separate installation when using MacOS
- clean user interface
- nice scrolling
- reading mode in both the desktop and the mobile version is very good for cleaning off the ads and images on a page and seeing just the text
- Lack of depth in developer tools in comparison to Google Chrome; this is the main reason I use Chrome for work on the Salesforce platform. Google Chrome can do more.
- Smaller apps market than Google Chrome
Most users I know choose safari because it's an Apple product. Others gravitate towards Google Chrome or Firefox for more technical capability with regards to web development. Users should use what feels right, but developers may learn that Safari is not as robust as Firefox and Chrome for web development. For everything else, it may be better because of its excellent user interfce.
When reading technical material on the internet, I use Safari because of the reading mode. I like that it increases the text size and contrast and cleans away the extraneous information on the page. Safari allows me to use Salesforce.com much the same way as Google Chrome. I use use Safari as a backup quite frequently to implement CPQ.
