santa lily vs santa rider?

Personally I prefer Jalter Lily as I didn't have a 4 star lancer except Fionn (who I don't care for and isn't good) and I didn't have a levelled up lancer of any level with AOE NP. She's also got an invulnerability skill and a 20% np charge skill, both very useful although I wouldn't expect to fire off a 2nd NP if I did bring her on a non farming quest.
Meanwhile Santa rider I don't know too much about but I hear good things, I know she doesn't have an evade or invulnerable skill or an NP charge but does have a better heal, guaranteed crit stars and I can't remember her other skill. Drake was my 2nd ssr I got, got ozy when he came out, Kintoki rider who's ST NP hits harder than Ozy and also have Medusa and Astolfo for more AOE NP if needed.
Basically it depends on what you need more, i needed an AOE NP lancer more and I like Jalter Lilly's kit more.
I don't need Quetzalcoatl but my luck with riders is great so I might throw in a ticket

Both are good at what they do which is set them up to fire their np's asap and clear the node ideally in 1 turn.

I guess jalter lily would be a tad better if you don't have something like a kaleidoscope (like me) since she has an np battery skill.

Both are very decent and work similarly (targettable heal, mana burst for their AOE NP).

Janta has some extra survivability, since her buster up gives invulnerability. And is even stronger than Mana Burst A-, but the NP multiplier of Santalter is bigger, anyways.
