This category is an easy win for interactive investor, it has one of the largest investment selections around with over 40,000 investments.
interactive investor’s investing options covers a wide choice of markets and assets. The only downside with ii is that it doesn’t offer fractional shares.
Unfortunately, one of the biggest drawbacks with Vanguard is that you can only invest in index funds and exchange-traded funds (ETFs), on top of this, you’re also limited to Vanguard’s own funds. So there’s roughly about 85 options and that’s it.
Winner: interactive investor (ii)

This is an easy win for Vanguard. If you look at Vanguard’s fees vs ii’s, there’s no comparison (and this is reflected in the overall Finder fee score).
Vanguard’s platform fee is extremely cheap at 0.15%, whereas ii charges a flat fee starting at £4.99 a month but rising to £11.99 a month once your portfolio reaches £50,000. The benefit with ii’s flat fee structure is that it can be good value for those with larger portfolios, however, Vanguard’s fees are also capped at £375 per year.
You can avoid ii’s commission fee by arranging a regular scheduled investment, but otherwise its commissions for shares and funds are a bit steep.
Winner: Vanguard

It’s a dead heat in this category. On paper, ii and Vanguard are fairly similar when it comes to ease of use.
Vanguard’s desktop and mobile app are pretty basic, but ii offers a more in-depth investing experience.
Winner: Tie

interactive investor and Vanguard offer quite similar tools, but ii has a bit more to help investors research and dig into investments. It also offers plenty of expert analysis and insights on the platform.
Both are lacking any sort of social features and Vanguard has no tools for investing or trading (because you can’t trade most assets or investments with Vanguard).
Winner: interactive investor (ii)
Overall winner: Is interactive investor better than Vanguard?
If you want a platform brimming with features and investments to choose from, then ii could be the way to go.
However, if you want to keep things simple and cheap, then Vanguard might better suit your needs.
It’s quite hard to separate these two because they both offer different advantages to suit different types of investors.
Vanguard edges a slight win here in large part due to the excellent value it provides investors with extremely low fees and this is reflected in its overall Finder score.
Winner: Vanguard
