Started off as 70% music 100% effect then one day decided to turn effect down to 0% and played like that for a week or 2. Now I range somewhere between 20-50% depending on how loud the map is. I like being able to just barely hear my hit sounds under the music. I also switched keyswitches during the time I had effects at 0% and my accuracy tanked so idk, probably a relation there. I find now that I can power through streams if I don't focus on hitsounds but they are nice for lining up downbeats on other things. I'm still too lazy to go back up to 100% music and readjust from there though so still at 70%.
