Domanda Microsoft Edge Vs Google Chrome

the absolute best instead for security so "anti malware" browser and the most privacy-friendly, and the "fastest"?
The browser used is irrelevant for malware unless it exploits some vulnerability, so keep it up to date, don't open downloaded untrusted files and don't worry.
For the most privacy-friendly you can read the official thread Best Web Browsers for privacy.
Which is the fastest is hard to tell because it depends on the hardware, the test itself and most browsers out there are based on the same Chromium source code. Most likely I would say Chrome or Edge for additional proprietary optimizations on top of the open-source engine.
