it is the best option on Android currently since Bromite is almost always a Chromium version behind whatever is current.

Right now Bromite is unmaintained and has been for a long time. I shudder to think how many versions it's behind.

If you want a FOSS Chromium-based Android browser, use Mulch. It gets updates fairly quickly and serves much of the same purpose that Bromite did, while actually having a (very slightly) larger dev team.

Edit: Oops. Didn't realize that Mulch doesn't have a content blocker. Someone else mentioned Cromite (which does have a built-in content blocker), so that might be a good option as well.
