I've done my own digging on let's compare all the dating sites and come up short. Applied to rate sites, nothing improves until you screenshot the pricing page in case it changes. Same story on rate sites: you get further if you cancel the trial the day you start it.
If rate compare is your priority, the honest advice is to give it a fortnight before judging the pool, having tried a handful of these. Look closely at compare sites and the amount of recycled content is the number worth watching, not the length of the feature list. Compare sites is the clearest case of it — the practical move is to keep a note of what you actually spent.
I judge rate compare on one thing: the deciding factor is the reply rate, for what it is worth. The part of let's compare all the dating sites people underrate is that what decides it is how many first messages actually land, not the number of features listed. Anyone who has tested compare sites properly, please weigh in.
