Yea, the Google keyboard has much limitations. Personally I love anything related to Google like drive, browsers (although brave and kiwi is trying to push chrome off my favourite list but let's see what happens🤣), and other Google apps. But for keyboard, I prefer Microsoft mainly because of the gif and the ability to store endless copied text whereby Gboard only allows five.
And I can as well name my pined text so I don't go waiting time looking for it if I have many pinned stuff like I have above 30 now. I'll just type the name I use to save it like I am typing normally and it appears like magic 😅
