Better gameplay okita or mhx alter

Okita is better than mhxa, that is for having a mana burst in quick form, a star absortion skill, evade as survival skill that at the same time buffs her crits, the NP ignores the defense buffs and debuffs the defense of that enemy

I need some information on what you mean gameplay wise. because if you just means stats and viability, okita is the clear winner here. however mhxa over time becomes quite fun and her animations and usefulness are also quite good and arguably if you wait far into the future her gameplay grows insanely with some later released servants. Okita can stand on her own now and is fantastic as a saber and won't fail you, mhxa is a lot of fun to play with but is definitely far more difficult to use and will take a couple interludes to become viable.

Few of the simplest things about their gameplay :

Big damage, fast and quick paced gameplay MHXA win. Plus you can bring her everywhere but with the cost of your survivability but it can be covered by your or friend supp. When she's on a Crit Party, she's unstopable and one things about her, it's " high risk high reward ''

for sustainable Gameplay Okita Win. In terms of damage, she only can deal double damage against Lancer and Zerker. You need a consistent Crit party to elevate her near to MHXA level in terms of offense. But you should worry less because she's not that squishy.

You need strong support to cover MHXA, we know she's very strong but if you don't have strong back up to protect her then you should choose Okita instead.

If you already have good support, good protection, roll for MHXA and then bring her to destroy almost everything.
If you have no support/underleveled supp, no tank/taunter, always depending on friend support so much, Okita is for you.

Bonus : both is a great servants but in this game, waifu/husbando > gameplay so roll for the servants that you love the most.
BTW, i play for the Memes and Waifu/Husbandos.
