Are There Any Unique Rules That Make Pickleball Different to Table Tennis?

In table tennis, the serve must bounce on both sides of the net before being returned, which, to me, seems a little bit harder than one bounce in pickleball.

Moreover, in table tennis, you must throw the ping pong ball at least six inches straight up without a spin and hit it on its way down. In pickleball, you can drop the ball from any height and hit it after it bounces, but you cannot toss it, throw it, or release it with more force to make it bounce.
