As for #emoji fonts, or technically speaking, the emoji implement, my favorite is Twemoji. Twemoji looks very beautiful on flags. Rounded rectangle flags looks much better than round flags implemented by EmojiOne in my opinion. As for Emoticons, I think Twemoji is better than Noto Color Emoji, too. Unluckily, the ttf font of Twemoji keeps its color only if it's used on a browser, or it will become black and white on local apps, on gedit for instance.
