If you can only have one: Quetz Vs Ozy!!

I'll have a quick go lol
I will go for Ozy anytime, because of Protection of Sun God. This skill is so good, it just make sure any of my servants that relies on chance skill will get the 100% buff eg. Umu

I admit I haven't played Quetz that much (since I don't have her), but I played her more than enough to make a choice, and it's Ozy.

He is an amazing unit, both in offense and durability. His self-buffs; along with his impressive stats, turns him into one hell of a damage dealer, all the while assisting and leading his teammates (more like retainers) with equally amazing buffs and debuffs. He hits hard, helps the team and stays alive. What else could anyone want? A 5-turn heal/40% defense up makes him one hard king to kill. Also, combined with his natural Rider passives, his damage output only increases with his massive crits and the star weight/gen that guarantees them. His NP cripples, stalls and obliterates his enemies.

I also like him lore-wise. He is a Gilgamesh that everyone respects not for his undeniable authority and power, but from his righteousness as a King who actually cares for his people. He takes difficult decisions for them, not for himself. Truly an admirable King.

Is hard to compare his to Quetz, which is another amazing unit (and waifu), but between them I'd definitely pick him.

Lol you don’t have to choose if you have both.

I like any servant with a big appreciation or interest in wrestling, so Quetz is my pick.

That reason aside though, I do gotta hand it to Ozy for his mad durability and attack buffs, and his np charge/buff chance for allies makes for easier NP chaining. He can easily fit in any team composition with his simple yet useful skill-set. Quetz seems more dependent on specific buster-based teams to deal more damage, but given that she can supply Guts and a Buster boost alongside Charisma, she's the right servant to use if you want your Buster attacks to hit harder.

Quetz has more niche to her set-up sure, but its a niche more than worth it if you can make the efforts to summon her.

Quetz has a higher burst potential but Ozy will be more useful after the intoduction of break bar system. With 58% atk up and 40% def up he is essentially a Berserker with Ruler Defense.

I have both but i enjoy way more Quetz, also she is adorable.

I got to side with Ozzy Osbourne. His party-wide attack buff, party-wide NP charge, and NP effects has kept my team alive every time I use him.
Quetz is a hard hitter, and I appreciate that, but I personally prefer servants that have skills that benefit the entire team.
Plus I just love seeing him smite enemies.
And his VA is just too good.

considering that their NP have comparable and similar effects, i'd go with the Feathered Serpent, because i love the ATK buffs more than the defense buffs, especially when i already have Memerlin, Waver and Mash on the team.
NPBB chaining Nukers with support suit my playstyle a lot more than a more balanced team, for me it's just build a little and then fire at will.

I have Quetz and let me give you an honest opinion.

Quetz is a almost purely DPS Rider, she can charge her own NP fast, has high Charisma and a 3 turn Buster Buff, has a skill to buff star absorption and crit damage and has the highest attack of all Riders.

Ozymandias has almost the same NP as her and has lower Charisma, but he has two things she doesn't: Protection of the Sun God and Imperial Privilege.
His 2rd skill can heal him and raises his attack by 40%. His 3rd skill charges the party's NP and raises Buff Chance, something very rare.

They're both amazing but serve different roles, Quetz is there to be a purely DPS and he has really good party support despite having lower attack.

I have Ozy. He makes QP farming easier. I don't have Waver, so he steps in to top off the NP if necessary.

But... I dance Samba as does she. For that reason, Quetz is on my wishlist. I'll get her some day. :)
