I've made quite a few post related to this, like; best 🔥 fire Users, best string users, best electricity users and so on. But let's leave that aside for now and go into anime ice users.
Unlike string and electricity there are quite the number of ice users in anime. Therefore I decided to rank them and give detailed information and explanation on their powers/abilities.
First let me say that ice carries a lot of potential depending on how it is used. It can be used for both attacks and defense. And it's attacks ranges from direct to indirect. It can also be used to a monstrous level. It is indeed a great element.
Let's move to our rankings
TOP 10 STRONGEST ICE USERS IN ANIME;
1. Aokiji
Devil fruit users have a great disadvantage, and that is the inability to swim in Sea water but aokiji has overcame that great disadvantage, he is able to freeze walk on water therby turning it to ice.
Aokiji is a logia type devil fruit user. Which means he can control the the ice and also become ice. Therefore hitting him would be impossible.
Aokiji is so strong that when he fought against akainu the whole island became half- frozen half-molten. That is to say his ice abilities have an incredibly great range and he can freeze almost anything and anyone instantly. The only disadvantage to his ability is due to natural phenomenon. For example fire melts ice and molten lava does that much faster.
2. Esdeath
She is a general in the imperial army. She derives joy from making people suffer in the belief of her father's saying "only the strong survives".
Due to the fact that she took her father's words to heart she became cold hearted and does not care for the well-being of others. Until she met tatsumi, who she fell in love with.
Esdeath has ice ability that can make her form and mould ice at will, she can create ice from nothing and use it to utmost perfection. Her greatest move/ability allows her to freeze time giving her a huge advantage over most opponents.
3. Toshiro hitsugaya
Toshiro is the captain of the 10th squad in the gotei 13. He has a relatively small stature, due to this he has been mocked which made him become cold hearted.
During the zampakuto arc in bleach, when toshiro's zampakuto saw him, it confirmed that someone that small cannot wield such power but it is infact his power.
He has the strongest ice zampakuto in the soul society and great amount of sword skill.

When endeavor was still the no. 2 hero all he wanted was to beat all might, the no. 1 hero. He ended up treating his son badly in other to fulfill his own desires. As such todoroki grew up hating his father. His quirk is called half-cold half-hot, it allows him to control ice on one side and fire on the other side.
Originally he hated hi father's side; that is, his fire side. But then after confronting midoriya his perspective changed.
Todoroki's is one of the strongest student in class 1A, he also has one of the best quirks in the entire series. His range in freezing is very huge, such that he was able to use ice to defend against the shock midoriya's shock wave attacks. He can also use his fire side to counteract the effect of freezing himself when using ice.
