I think the comments you've had so far have been to do with the result of having a good-looking and functional presentation. But as a fellow Keynote user, I understand that it's not about the end result; it's about the joy of working in Keynote. Hell, that's the thing about being a Mac user — when It Just Works™, It Just Works™ to the point that when you try to do things the other ways, somehow It Doesn't Work Well Enough™ even if the result winds up identical. I can manipulate and place objects in Keynote with a precision that nothing else affords me not because they're incapable of it, but rather because their workflows for doing so are, to me, hugely inefficient. The way Keynote handles layout, snapping, movement, Magic Move transitions and many other features just can't be replicated. Except it can, on the web. Have you given iCloud.com's version of Keynote a try? Much less featureful, but if you go back to any given Mac and make yourself some nice templates and store them in your iCloud Drive, you can always use those to create presentations in _basically_ the same workflow as you're used to, just in a browser. Fair warning, though: anecdotally, I've always found it's a bit heavier on the resource usage than Google Slides or Office 365.
