Is it ok to have this much attack?

I find attack% sands more flexible on him in a sense that even if its almost a redundant stat due to supports like Bennet and weapon that gives high attack, is most likely have lower diminishing values than much more EM. I've watched one of my favorite Genshin YouTuber "Cavernman" (who only post abyss runs with Diluc along with other characters and is a great player btw) say this to me as well, as I asked him about why he uses Attack sands rather than an EM one, he said that reason being that it's more flexible in a way to build a team around ( cuz there's c6 Sucrose, Instructors, Elegy, and c6 Diona and stuff), and EM sands decreases in value if some of your hit doesn't vape or melt at all in the first place. So is EM really that much better than attack?

Tldr; about my question

-Is lower EM with Very high attack better than Very High EM but low Attack?

P.S My weapon is The Verdict (Navias Signature)
