Best Portable Browser for Specific Needs

[kendall.a]

I know that we have a great collection of portable apps over at the main site. In fact, we have a best free portable browser section (http://www.techsupportalert.com/best...ternet-Network).

However, I'm looking for additional recommendations from those of you who use portable browsers. My needs are based upon the following:

1. Multiple devices--works on multiple platforms (linux, android, windows 8.1)
2. Multiple devices----ability to be sync bookmarks/settings across multiple devices (desktop pc, samsung android tablet, surface pro 3 (work), linux laptop)
3. Is portable and relatively small (both desktop pc and surface pro 3 have 128 GB SSD's).
4. Is not Firefox (or a Firefox clone). (For personal reasons.)

I've been using Maxthon for a couple years now, but I am having more and more minor annoyances/inconveniences with it of late. So, I am now trying portable Chrome and portable Opera. I have always found installed Chrome and even portable Chrome to be quit slow to load and CPU/RAM heavy. At this point, I'm leaning towards portable Opera.

Thoughts?
