Editor's VerdictSidekick isn't even in the running anymore since it was acquired and shut down, so you're left with Firefox by default if you have to pick between the two.
Firefox has its downsides, like fewer extensions and some website compatibility issues due to its low market share and non-Chromium engine, but at least it's still available and maintained. Sidekick's productivity features are outdated and, more importantly, the browser itself is no longer supported.
If you need a browser from these two, Firefox is the only real choice.
