You need a feature outside the focus

Each WordPress category has a feature spectrum.

Support response has slowed you down

Support quality is the hardest thing to read from a listing, and it is the most common reason a switch gets made. Read the most RECENT reviews on each alternative's profile rather than the lifetime average — recency is what tells you how the app is supported today, and trailing review velocity is the freshest signal AppRanks tracks.

Your scale has changed since you picked

An app chosen at small scale is not necessarily the one that survives growth. Once catalog size, API rate limits or data-sync volume start to matter, the higher-ranked apps above tend to be the longer-established ones, which is a proxy for how much scale they have already met — not a guarantee. Check each candidate's recent reviews for scale complaints before you commit.
