First of all you measure NP not by percentage but by turns needed to fill bar from 0 to 100%

2nd Np gain vs arts up are entirely relative to the servant depending on few factor that is the servant deck, card perfoemance and their crit tendency, main point to note about those 3 factors is that Arts up only affect NP gain from arts, however NP gain up affect ALL cards type and most probably from being hitted too.

For the deck it is obviious that only zervant with dominant arts deck will benefit better with Arts up, however there's 2nd factor which is card performance, for this you need to note the servant quirk, for example both Shiki gain reasonable NP from arts and quick, Scathach gain more Np from buster compared to quick,etc. Lastly the more pften the servant crit the more pronounced their quirk will be..

Third is that there's simply servant with BAD Np gain, like the zerkers and even AAA type like Tamamo and Marie casters.. these type are without doubt are better suited to Prisma cosmos.

Answering the question tho Arts up are better for Jeanne, her deck are AAA, her main Np gain iz arts and she crit pretty often.
