What's best staff for mage?

[YourMouth]

Hello! Every guide says that Court Sorcerer's Staff is best for mage because it has S scale for intelligence.I just don't get it.Who cares what scales it has,for mage you only need Spell buff.
My Heretic's Staff at +6 deals much more magic dmg than Court Sorcerer's Staff at same +6.But it has A intelligence scale , so that's why people say its not that good.Help me understand that

Guides are usually hit or miss, you're right that Spell Buff is mainly what matters.

So the scaling for each staff also depends on how much INT you have, meaning some staff get more spell-buff scaling between, say, 28-34 INT, making them the best choice at that specific INT level, and then another staff is better at 35-42, etc.

Each staff has an optimal INT level, the reason people say Court Sorcerer's Staff is best is because after ~43 INT and +10, that's where it maintains consistent scaling while other staves don't.

I don't remember the optimal INT levels for each staff, but there was an excellent table(graph) I found before which clearly displayed in green which staffs were best at each INT level, but after a quick search I couldn't find it again unfortunately.

EDIT: I did find something similar Here[darksouls3.wiki.fextralife.com]
Essentially says best Spellbuff staffs for INT:
30-33 / 45-50 - Sorcerer's Staff
34-44 - Heretic's Staff
50+ - Court Sorcerer's Staff

It depends on what lvl you are. If you are still low lvl with a low intelligence score, scaling won't matter much, but eventually, as you start leveling your intelligence, scaling will matter quite a lot.
