Firefox has a lot of telemetry built into the default install. It has Pocket, everything you type into the search bar gets sent to Google by default, phones home to Mozilla by default, I could go on. Ungoogled Chromium doesn't do any of that. Firefox is also less secure than Chromium. If an actual malicious attacker can access my browser, that's a million times worse than any kind of concern about Google bulk collecting my data as far as I'm concerned.
