Score = average tier (S 4 · A 3 · B 2 · C 1), shown as the letter it rounds to. Cells shade by how many of that topic's channels sit in each tier. Topics with fewer than 3 channels are dimmed and listed last. Click a row to filter the list.
Rankings and descriptions are from "Youtube Sub Quality" (S, A, B and C tier lists). Counts here are taken from the lists themselves; the document's metrics page (S 15 · A 76 · B 49 · C 20) predates them. bikingdc sits in the B table but is marked C, so it's counted as C. The Void appears in A (internet horror) and C (true-crime stories) and is kept as two entries. Topics are read from each description: formats (video essay, mini doc, stories…) are dashed tags, subjects are solid. Channel names open a YouTube search. [build 2026-10-08a]
