a zid, thank you for your neat summary.
I must add
1a) Minhag Ashkenaz, (aka Yekkes) put on with a brocho.
2a) Oberlanders are not chassidim, as they daven ashkenaz. (This may start something rolling…)
5) In EY no body puts on, because there Ashkenaz follow the Gra (also in duchening, special shir shel yom for yom tov, ein k’elokenu at the end of davening, etc), and sefardim follow Maran Bet Yosef.
