What is the best input method for mobile phones?

Useful mobile phone input methods include: sogou input method, Iflytek input method, Baidu input method, QQ input method, TouchPal input method, universal five-stroke input method and so on. I think the best mobile phone input method is Baidu input method, which can be associated with many characters. It's very good to use, and there is a keyboard sound when typing, which is very nice, and there are many beautiful keyboard skins to change. I like Baidu input method very much.
