Bear in mind that unless you uninstall all of Google's system-altering components, Google will continue to harvest and upload your personal information, whether you use Chrome or not. You can quit the Chrome browser app but those processes will continue to run constantly, while also periodically updating themselves.
Chrome is the Trojan that installs Google on Macs. If you like the Chrome browser and prefer it to Safari, there are other Chromium-based browsers that do not require Administrator approval for the installation of constantly running background processes. Only Chrome does that.
As for protecting your privacy, nothing is better than Safari: Safari Privacy - Apple.
Constantly uploading your browsing activity to Google's command-and-control networks probably contributes to Chrome's overall slower performance too.
Why people would choose to buy a Mac only to cede its privacy and security advantages to Google remains an enduring mystery.
