I'd say some of my favourite taiko mappers (In no particular order) are...
Firce777
Easily one of the better mappers in the community right now. Barring some of his crazy Firce Force difficulties, he pumps out really quality maps that cater to several groups that are playing Oni and beyond. He has a really good sense of rhythm and implementing patterns that are fun to play. He's also probably one of the most structured mappers when it comes to streams. They almost always flow well and have very understandable patterning.
Lepi
One of the core mappers when I had first gotten into taiko. Always produced good difficulties despite back then there not being many taiko mods, so had a very clear sense of direction and what he wanted to achieve with his maps. This is still true even now, as any mods on his difficulties will pretty much always have an explanation as to why it was done a certain way.
Nyan
A really underrated mapper in my opinion. Nyan, much like Firce, pushes out really good difficulties for higher level Oni players. His patterns might not always be the most intuitive, but they're always fun and keep to the music, and are never too overbearing (his maps are always possible to FC, even if your skill isn't at the point required to FC them yet).
OnosakiHito
I generally have very mixed opinions about Ono's maps, but the sheer truth of the matter is he was, and still is, one of the core mappers in the taiko community. He maps in multiple styles and is very open ended with how he approaches a map. He has created a large majority of the maps that are currently ranked for taiko (including guest difficulties in this), and they're most of the time a pretty good quality
Kana and Climbb
I can't mention these two separately as their collab diffs are why I consider them great mappers. These two show time and time again that multiple styles can be used in a map, and the map can STILL be intuitive and fun to play. I've always found myself in for a treat when I've played maps from these two.
TKSalt
What can I say about TKSalt that hasn't been said already? His maps are similar to my own style, and are very drum rhythm orientated. He has some of the best entry and mid level Oni difficulties that are on the rankings right now, and as time passes, will probably the mapper that everyone suggests to start with when people are starting to get into Oni level difficulties. That said, he can map harder difficulties as well, and they're just as well made as his standard Oni difficulties are.
- Kagami Yuki -
While this person has very little maps currently ranked. I honestly feel that the maps they make are on par with some of the better mappers. One of their maps intrigued me so much that I pushed for them to go for rank, as it played VERY well for someone who had never ranked a map before.
