Arrow Dancing vs Phase Acrobatics

Wondering which is more useful on a Skin of the Lords for a ranged eva-based character. I'm guessing Arrow Dancing would be cheaper, so there is that. But those considerations aside, are spells or physical projectiles more dangerous?

Edit: Might be worth noting that I'm using Atziri's Step and Ascent From Flesh.

Spells. Definitely spells. Besides, it's easier to grab arrow dancing than it is to get phase acro. If you're only looking for phase acro though, "The perfect form" might be a really good option.

Edit: Forgot to mention why. You can already evade projectile attack. However, evasion characters hate one thin in particular: any ability that guarentees a hit on them. One way to achieve this is resolute technique (can't do anything there), another one comes in the form of spells. And that's why you want spell dodge.

Alright, thanks.

There is a loot of spell based projectile monsters.
Evasion players get use to igonoring most of attacks and then get destroyed in split of a second from thos vaal monsters spiting chaos projectile spells.

Spell dodge is rahter hug thing becouse game is balanced araund 75% rest, but thats nothing realy and best you can is provent fast multiple attaks kiling you where stronges one shots still got chance of geting dodged.

People who ignore phaseacro get unlesently suprise when they get in front of vaal monster offscrean barage and get reduced to ash in instant.
