Honestly avatar attack has been shown to do very little. It does help, but not much. Avatar accuracy is probably the safest bet, unless you think you're capped in almost all cases then either go for avatar attack or avatar m.acc.
Most people do avatar m.atk & avatar acc. Personally, I went 10/10 physical and don't have any magic attack merits, but I use the merit BPs less than most people do I think. (Yes, I have 5/5 Heavenly Strike, Beyond/Ultimate/Minikin atmas, Pet:MAB+12 Shareevadi, etc... but even so, I don't find the magic ones to be that effective in the situations where it really matters.)
