what foolscap do you use?

i'm a person who wants to know many things, no matter how useless or strange they may be. lately, i've been obsessing over what foolscap I should use for my tutorials. (💀) i've been rotating between my jc foolscap, azone, campus, and the free foolscap that tuition centres give out every so often. but, still undecided. as autistic as this sounds, thinking about what foolscap to use has wasted a lot of my time and some times even kept me up at night.. so I need to know, what foolscap do you guys usually use?
