This is a very common casual part time rider impression. And for a beach cruiser or slow grocery getter it's perfectly acceptable where you don't need to push a lot of energy into the pedals. I know that the free ride mountain bikers have low saddles too but that's to let them move around on the bike more easily and they rarely sit except in spots where they don't need to do their particular sort of gymnastics to get over stuff.

However you'll find that if you start riding harder on a road use bike that the higher saddle makes a LOT more sense. And you don't need to take our word for it. Your knees and thigh muscles will tell you soon enough. Nobody that rides seriously has a saddle that they can sit on and still touch the ground with more than perhaps the barest end of their toes.

Try it, you'll see what we're saying very quickly. Then go looking at some of the setup tuning for proper positioning to max out your body's fit to this new way. And then just get used to sliding forward off the saddle at stops.
