As a power-excel user I agree with you that Sheets isn't quite there yet. Trying to use the same shortcut keys that I'm used to often makes me want to bang my head against a wall, either because they don't work at all or because even if they do, it's not as responsive.
However, the pace of improvement is one that I think you should definitely consider before saying "never." Excel hasn't fundamentally changed for me since 2003 (outside of being able to more easily handle larger datasets from 65K+), so it seems like a fixed target while sheets continues to move closer (still with large gaps ahead!).
If I need to do financial modeling, I'll likely continue to use excel. However, for many low-touch projects, I've almost completely switched over to sheets, which wasn't the case even a year ago.
We use excel with pivot tables to explore data. The previous google sheets had such low limits it was pointless. The new one helpfully says "Sorry, an error occurred when opening this file. Please try again." on trying to open a 40MB uploaded CSV. Back to Excel I guess. I also LibreOffice on my Linux machines, but it is slow, single threaded and harder to use with pivot tables.
