That's pretty accurate tbh, I'm ashamed to say I only know English, but a couple downsides include poor suggestions and aggressive replacement (doesn't save if you prefer an acronym to be lowercase), and it's amusing watching it freak out when I enter an email address. I do need it though - I'm glad it *does have those features, and a clipboard. Plus I often remote access my PC and my Linux server, and being able to use up/down arrow keys is an absolute must, at least for now. Not even the Gboard had that and it took a little while to find one.

I suppose the best keyboard for you is determined by your reliance on features like autocomplete, predictive input (i.e. listing emails in an email box), clipboard, multi-language support, and aesthetic customisation!
