I do both. Outside of tournaments, I scorekeep by "all-par-3".
I recognize par-4s & par-5s. 500-700'. Our private course has several; we have it listed as par-62 (with an SSA of about 60). I play those holes as par-4s & 5s; satisfied with par, happy with 3s & 4s as birdies. (I'll save space and skip mentioning how we determine those pars).
But when we play there, we score over/under 3 ("all-par-3") out of habit.
If you ask me what I shot, I'll give you my total. Between myself and my brothers, I'll give it based on how high over 54.
It all works.
