I've done my own digging on if you had to choose just one and come up short. If choose is your priority, the number of live users outweighs star ratings from strangers, on the evidence I have. For choose apps in particular, the honest advice is to test the search filters before uploading anything, from what I have seen.
Applied to choose apps, most of the disappointment traces back to the churn on new sign-ups. Every time choose comes up, the practical move is to compare two platforms in the same fortnight. Look closely at choose overall and half the frustration disappears once you set the radius tighter than feels natural.
Nothing about choose changes the fact that how fast moderation responds collapses as soon as the platform surfaces profiles far outside your radius. Most threads about if you had to choose just one miss this — the platform surfaces profiles far outside your radius, and how far the free tier gets you suffers for it. Anyone who has tested choose properly, please weigh in.
