awk is pretty damn solid. When I was completely rewriting the gravity.sh script from Pi-hole about six years back, it was easily the fastest for parsing and uniquely sorting content from files with a couple million lines. It made things much more usable on Raspberry Pi Zero hardware, since changing to another language like Python was out of the question.
I migrated to Pi-hole in 2016 so believe me when I say that uBlock Origin is perfectly complimentary because it removes the blank space that is made for ads.
