Brotli has been extremely successful thanks to its implementation in the woff2 font format to encode the glyph information. At similar compression levels, Brotli can compress much faster which is a boon when serving large amounts of text contents such as APIs or just Web experiences. Note that assets such as CSS and JavaScript scripts can be pre-compressed to avoid the latency increase, CPU usage and suboptimal experience of on the fly brotli compression.
If you can set it up on your servers, please do.
