The problem I find with super funds like Netwealth, unisuper, etc. are the fees. Typically the annual investment fee is around 0.5% of the total funds. So, if you have $1m in your super fund invested in the market, out goes $5,000 every year to the super fund in fees - even if you had a bad year and got a negative return. If your super fund is in accumulation mode another 15% of any earnings also goes to the ATO as tax.
A SMSF costs less than $1,000 in annual fees and the brokerage is a little and $3 per trade which can save you $1,000s in brokerage (see link below). The low brokerage cost means you can change or rebalance your portfolio more frequently and at lower cost to maximize your gains.
