What are the best ranked 10 Xyz monsters (Yu-Gi-Oh!)?

It’s not much of a contest, there are only 3 Rank 10s with higher attack, none of which are worth mentioning for their own reasons and this card effect, It’s immune to everything. None of your card effects will do anything to this guy, making him extremely troublesome to deal with since that amount of protection is usually not paired with that much ATK

To rephrase that: When given the opportunity to summon any monster from the entire pool of the main deck and extra deck boss monsters, people chose to summon this guy
