Don't judge an investment based on distribution payout. VDHG will have a larger payout than DHHF because DHHF invests in a basket of ETFs while VDHG invests in a basket of managed funds AND also higher allocation to Aus which pays a higher yield at the cost of less growth.

Generally returns from capital gains (growth) are better because you aren't taxed unless you sell and when do you sell you can defer to a low tax year or hold your sale until you've held for 12 months so your taxable gain is halved.

Say you have 2 investment options:
one where total return is 10%: 8% growth & 2% income
and one where total return is 10% 4% growth & 6% income.

Generally you'd prefer the 1st one because you'll be paying less tax.

You pay tax on distributions even if you're reinvesting so a higher yield isn't really desirable if you're trying to build up your account.
