If you are looking for solid and stable Android 6.0 Marshmallow ROM with root working out of the box, definitely check out the latest Chroma ROM, which I am using as daily driver on my Google Fi.
Based on latest Android 6.0 Marshmallow, Chroma ROM brings you the latest Google OS along with performance boost that you will appreciate. In my testing, the Chroma ROM faired much faster than the stock Android 6.0 firmware and this is definitely a beastly custom ROM I recommend you to try.
The Chroma ROM does offer a few customization options including System UI Tuner/Developer options enabled out of the box, and tweaking to your status bar, navigation bar, volume rockers, and gestures. You will also get some nice 3-finger gestures for screenshots. For launcher, you also have an option to rotate your home screen, which is nice for landscape usage.
Overall, Chroma ROM has done it again with Android 6.0 Marshmallow, bringing you the better-than-stock experience with root working fully out of the box so definitely give this guy a go this week(end) and do let me know what you think! (But I think you will love its super-zippy performance and excellent battery life!)
