Its hard to put into words but basically it's real vs. imitation. Like anything imitation, egg beaters, sugar substitute, etc, they are good. But not as good as the real thing.

There's not much surprise or variation in using a dildo/vibe, usually similar actions are used each time. The woman knows ahead of time just how she'll use it and even when & how she'll make herself cum. Now you on the other hand can vary what you do, keep her guessing, work her into a frenzy begging to cum, finally allowing her to, and then hold her close, kissing & cuddling and starting all over again.

That might have explained it....... ability and attitude.
