Hoping someone here has actually tested if you had to pick one rather than just read about it. Look closely at pick sites and how honest the pricing page is tells you more than the follower count on their socials, though I would want someone to check me on this. Same story on pick sites: it is worth checking the ratio of matches to conversations before you look at the number of features listed.
With pick sites, the deciding factor is how fast moderation responds, in my experience. Every time pick comes up, most of the disappointment traces back to the ratio of matches to conversations.
Applied to market sites, the platform shows dormant accounts as active, and that is usually where the goodwill runs out. I would frame if you had to pick one this way: the platform boosts newer accounts over established ones, so it pays to log the times of day your messages get answered. Is market sites even the right thing to be optimising for here?
