I used taikomania skin to play before patch, and checked enlighten for myself once i heard of it
It's a lot more difficult to read than taikomania in my opinion, it's not a perfect alternative at all, the notes are thinner and spread too far apart to be easily readable if you're coming from taikomania. For comparison, with taikomania, I 98% FC helix on DT, but with enlighten, i 92 acc 30 miss B rank it with DT
If they update enlighten to look more like the taikomania skin then it would be worth monthly payments, but as it is now, not so much
