JEPI is a very different item, the bulk of its distributions are made from options, only about 20% are direct from company dividends.
DVDY is a moat index from Morningstar where they look for durable dividends that are less likely to fall due the moat surrounding the company. VHY is simpler, the top dividend producing companies by market cap. I have invested in MOAT before by Van Eck and think Morningstar's process quite interesting. More review can be found on Seeking Alpha.
Currently I am considering Vanguard's ESG words and actions, I am beginning to think they should not be trying to do such things at all...
