CSROI vs CSStonks: which CS2 case tool should you actually use?

Both sites cover CS2 cases, but they answer different questions. CSROI tells you the expected return of opening a case right now. CSStonks tells you what supply trends are doing to that case's price. You probably want both — here's when to use which.

Verdict

They're complements, not competitors. Pull up CSROI when you're deciding to crack a case today; pull up CSStonks when you're deciding to hold one for 12 months. If you only ever check one, CSROI for active traders and CSStonks for long-term case investors.
