Rumia- - This guy is really special for me. He used to help me when I just started mapping in 2015-2016, he was making really unique maps back then although he's not really active nowadays.
Gillstar - Mapper with exquisite song choise in my opinion. Also he likes Jounzan!
0ppInOsu - Mapper who has been behind the scenes all the time before like a year or 2 ago when he proved that he can make something unique and visually pleasing. Also he's really active considering for how long he's building his professionalism.
Yuguiboy - One of the first if not the first Halgoh's mentee that learned slider theory for sliders to not only look visually pleasing but also represent music accurately.
MaestroSplinter - This mapper mastered purity & enjoyment both combined in a perfect balance.
nexx- - Sadly this mapper has small nubmer of audience but as long as I know him he can create something beautiful and unique but only if he has true desire to do so.
KogumaX - Unrepeatable in a way of placing objects. He perfectly combines old mapping style with fresh ideas.
Ykybfz - As long as I know this guy didn't really built himself yet but I recommend you to check his other maps because he's on the right way!
Djulus - DJ ulus. Solid mapper although he didn't really experimented making something unique or fresh but I could say his style never gets old.
tukamoto7km - Second unrepeatable mapper in this list. This guy truly mastered representing almost every noticable sound in songs by little tumours on sliders or somehow differently it doesn't matter at all, he just perfectly making it.
Frakturehawkens - Mapper that experimenting with his style a lot, he can explain every little detail in his map and that is respectfully for sure.
Blacky Design - Earned his recognition not long ago. I believe he's on the way of building his own style because he has some cool and fresh ideas and has lots of courage.
colicen - The most talented person that i know. His mapping style earns recognition of hundreads or even thousands of eyes and I think he is still underrated to be honest.
taku Not only profficient mapper but also respectable player. I could describe his style in two words - "Solid Tech"
Sharu - I remember this guy to make some high quality and interesting maps but then he poped off with new "tag" style and personally I think that this style is just mindblowing. Big respect!
Skystar - An old classic. Lots of mappers all over the world looked up to him because of his freshness he brought to a mapping scene years ago.
Halgoh - Not gonna lie this guy is my favorite in this list. He did something not everyone could do. He was building his own style for years and finally earned recognition he truly deserves! But what I appreciate the most is that he didn't stop after recognition, he continues to improve his style by himself.
