I have 11 "primary" kits, each on all four of the main testing platforms (and another ~40 secondary kits). I don't regret any of the costs I've incurred. I don't think we can say, with any universality, that something "isn't worth it." Whether it's worth it depends on how much of a genealogy nut you are. I can definitely say MyHeritage is the least useful of the platforms right now, both because there aren't many other folks on it (after all, we're not really paying to have our DNA done; we're paying to find "DNA cousins," so database size matters) and because their matching algorithms seem *drastically* imperfect (finding way more matching DNA--double, sometimes triple--what the others detect). I pay for Ancestry both because that way I don't have to fool with asking folks to share their trees, and because I do use the databases quite a bit (which is even more useful now that FTM can auto-search not only Ancestry's databases but also FamilySearch's). 23andMe has become less useful now that it has no single inbox and you can't simultaneously work on different profiles in different tabs, but OTOH its "relatives in common" is dynamite. If someone seems engaged/interested/involved, AncestryDNA or 23andMe is usually the best start point (because, big databases). When I'm buying a kit for a cousin who doesn't care, I go for FTDNA because it's the one I'm most assured of keeping control over (in order to get it onto GEDmatch to be able to triangulate on). The short answer is probably "any DNA platform's fun to be on, and the more you're on, the more fun you have."
