I am using gzip despite CRIME/BREACH because Brotli has caused me a lot of issues: after a couple hours (for busier servers), or a couple days, Nginx uses 100% CPU, and the sites become unresponsive.
This is a long term issue, and the only way I found to stop worrying about my servers performance was disabling Brotli and reenabling gzip.
Your mileage may vary, and I really hope you have better luck than I had.
