VOO vs. VTI vs. SPY: What Actually Differs
A structural comparison of three of the most popular large-cap and total-market funds.
Category
Once you understand the basics, the next question is usually 'which one?' This category compares specific funds, fund families, and brokerage platforms head-to-head, using published fee schedules and prospectus data rather than marketing claims.
This category is aimed at readers who already understand what an index fund or ETF is (see Index Fund & ETF Basics if you don't yet) and are now trying to choose between specific, named options — a particular fund, a particular brokerage, or a particular way of managing a portfolio day to day. Rather than publishing a single static 'best of' ranking, each guide here explains the actual criteria worth comparing — expense ratio, index scope, account features, ownership structure — so the comparison stays useful even as specific providers change their pricing over time. If you're deciding where to open an account or which of two similar funds to buy, this is the category to work through before moving on to portfolio-level strategy.
