Key differences at a glance
Neither IOO nor VGS is the "right" pick for everyone; it comes down to what you want from the holding. Where they differ most:
Category scores compare these two ETFs only and are not absolute ratings.
VGS has the lower management fee - the one objective "cheaper" axis.
VGS is the larger fund. Larger is not inherently better, but greater scale can support tighter spreads and lower closure risk.
VGS spreads exposure across more holdings (IOO 117, VGS 1,252); the other is more concentrated. Neither is inherently better - it depends on whether you want breadth or a focused tilt.
IOO distributes approximately 1.08% and VGS approximately 1.6%; VGS carries the higher estimated distribution yield. A higher yield may suit an income focus; a lower one may suit a growth or tax-efficiency focus. Yields are estimates and are not guaranteed; past performance is not a reliable indicator of future returns.
Green highlights the factually lower fee or higher scale/income figure. Performance is never highlighted. Data from issuer disclosures, reviewed quarterly.
Yield figures are estimates based on recent distributions and may vary. Past distributions are not a reliable indicator of future distributions.

IOO tracks the S&P Global 100 Index, holding approximately 100 of the world's largest companies. VGS tracks the MSCI World ex-Australia Index with approximately 1,250 holdings across developed markets. IOO has substantially higher concentration in its top holdings than VGS. Both exclude Australian shares and emerging markets.
Investors comparing concentrated global mega-cap exposure against broad developed market index exposure.
IOO and VGS have approximately 43% estimated holdings overlap (estimated, limited data). This is considered moderate overlap, estimated from listed top holdings rather than the full constituent lists.
VGS has the lower management fee. IOO charges 0.4% per year ($40 per year on a $10,000 investment) and VGS charges 0.18% per year ($18 per year on a $10,000 investment). The difference is $22 per year per $10,000 invested.
IOO (iShares Global 100 ETF) manages approximately $5.7B and VGS (Vanguard MSCI Index International Shares ETF) manages approximately $17.2B. Fund size can affect liquidity and bid-ask spreads but does not by itself change the management fee.
You can hold both, but with approximately 43% estimated holdings overlap the two funds share a moderate proportion of holdings, so there is some duplicated exposure. Whether that suits you depends on your own objectives.
There is no universally right choice. It depends on your goals, time horizon and existing holdings. IOO charges 0.4% and VGS charges 0.18%, so VGS has the lower management fee, and they have approximately 43% estimated holdings overlap. Compare their fees, holdings and sectors above and consider each fund's Product Disclosure Statement and Target Market Determination.

This comparison and the ETFLens tools on this page provide general information about two exchange-traded funds and do not take into account your personal objectives, financial situation or needs. It is not personal financial product or investment advice. ETFLens does not hold an Australian Financial Services Licence (AFSL). Holdings overlap is calculated from each fund's published holdings (full lists where the issuer publishes one, listed top holdings otherwise), and fee data is sourced from fund manager PDS documents and updated quarterly. Past performance is not a reliable indicator of future returns. Consider each fund's Product Disclosure Statement (PDS) and Target Market Determination (TMD), and seek advice from a registered tax agent or licensed financial adviser, before making investment decisions.
