It is worth remembering that both distributing and accumulating versions can produce UK taxable dividends, if you are a UK resident. People sometimes forget that the dividends that are reinvested in accumulating funds are nonetheless taxable. As the tax free dividend allowance is reducing to £1000 next tax year, and £500 thereafter, more and more people may have taxable dividends in an invest account.
Personally, in a taxable account, I prefer to own distributing ETFs since the taxable amount is more transparent. With accumulating funds I have to look up the dividend at the issuer’s website and adjust my cost basis.
See FAQ for Tax in the United Kingdom
There is a section about taxation of ETF dividends.
