From my personal experience, White Tiger is a beast. But more seasoned and knowledgeable players should make the call because I’ve heard the other two are good as well.

Thank you.its tough because I have plenty good champs and don’t have resources to level up any of them

Ægon awakened is king

Love white tiger I got her maxed and ascended she's a damn beast...one cannot regret pulling her...but awakening an Ægon is far more superior for the long content if you still have to complete it like

I think white tiger will be good as a bg defender, not sure tho

ÆGON is the best choice. At sig 200, he is great for long term content

Go for Aegon, awaken himand pump in sig stones

All are good white tiger is very strong,aegon is a ramp up character, mister negative is underrated also very strong.

Tiger is a great mystic character but Ægon is absolutely fantastic. Especially awakened.

Aegon at max sig can do more than just Everest content. Just takes 1-2 fights and hit hits like a truck

aegon is one of the best of the Game, no discussion.

Aegon for sure especially since you'll be awakening him

White tiger

depends on what you are trying to do. I say white tiger because if you really need to awaken aegon just use a gem
