WebDecks vs Google Slides
Of the alternatives here, Google Slides is the closest to WebDecks. Both run in the browser with nothing to install. The honest differences come down to accounts, how .pptx files are handled, privacy and collaboration.

Which should you use?
If you need several people editing the same deck at once, Google Slides wins. WebDecks has no real-time collaboration yet, and that is a real gap.
If you'd rather not sign in to a Google account, want your .pptx to open without a convert-to-Google-format step, and prefer your files to stay on your own device, WebDecks is the lighter, more private option.
Honest note: WebDecks is newer and intentionally simpler. No real-time collaboration yet is the headline caveat versus Google Slides, but no account and native .pptx are real advantages if you want them.
