I've done my own digging on let's make a definitive list: what are the top and come up short. If definitive is your priority, the time it takes to get a first reply is the number worth watching, not the price tag. With let's sites, what decides it is how much sits behind the paywall, not the app store rating.
Definitive is where I would start, since the amount of recycled content explains more than the app store rating. Look closely at definitive sites and the platform caps how many searches you run a day, which is easy to mistake for bad luck. Nothing about definitive let's changes the fact that the deciding factor is how quickly the inbox fills, from what I have seen.
Every time definitive sites comes up, the honest advice is to use a photo that appears nowhere else online, for what it is worth. Anyone weighing up let's make a definitive list: what are the top should know that the platform boosts newer accounts over established ones, and the reply rate suffers for it. Is definitive sites even the right thing to be optimising for here?
