Sorry to keep you in suspense. I know you all couldn't wait. On further consideration, here are my new browser rankings on the Mac:
1. Chrome
2. Firefox
3. Safari
Chrome moved to the top from using a beta version of Apple's iWorks suite (Pages, word-processing; Numbers, spreadsheet; Keynote, presentation), on the Cloud, scheduled to be released this fall. This makes this software available on Windows-based machines, as well as on Apple, via the web (and iCloud). This is something people who use both Windows and Apple might most consider. I have used Google Drive and Microsoft SkyDrive a fair amount. I have planned to do a lot more with such web-based word-processing and spreadsheet software. I now plan to use iWorks primarily, instead.
The dark theme I have on Chrome, together with a similar look on iCloud (iWorks) is also sweet. As is the bookmark sync between between the Dell and the Mac.
Perhaps from sensing my thoughts or maybe from reading this post on Pages for iCloud where I first composed it, the nice people at Google also conveniently turned on the "Show Apps Shortcut" option -- with no direction from me -- showing the link on my bookmarks bar to the Chrome layout most similar to iCloud.
Firefox I will still use daily to read the news and my RSS feed. It is still most convenient to add items to Zotero with just one click or two.
Safari I will still use and set up primarily for the iPad. I added an Iowa State theme yesterday to try to salvage more Mac-based usage.

But it probably makes most sense for me to focus my web usage primarily on both Chrome and iWorks. A more focused, more exclusive approach is also consistent with Chrome's simple, yet highly functional layout.
