Is gccgo really faster? Last time I looked it looked like it was abandoned (stuck at go 1.18, had no generics support) and was not really faster than the "actual" compiler.

Digging around, looks like it's workload dependent.
For pure computational workloads, it'll be faster. However, anything with heavy allocation will suffer as apparently the gccgo GC and GC related optimizations aren't as good as cgo's.
As of about five years ago gccgo was slower for almost all workloads: https://meltware.com/2019/01/16/gccgo-benchmarks-2019.html
