Honestly, I think they are blown a bit out of proportion around here and on reddit. Most of the time it doesn't matter, and if it does, it's on the margins and only rarely.
Speed exists as an outlier since it's this binary +100% Damage Dealt / -50% Damage Taken toggle, basically. It's part of why I was really, really, really hoping they'd do more with the stat duels? More options for specific stat specializations to stand out some to change combat. Besides Specials like Bonfire / Ignis, Iceberg / Glacies, etc. letting them use them offensively (and outside the weapon triangle and mitigation!), anyway.
