If you compare it to filming with a DSLR setup, you have all these different parts you have to put together before you can start filming. The VX is just straight out of the bag ready to go.
MiniDV tapes are also the best back-up of all your footage imaginable. If you compare that to filming on SD cards where you have to clear the card every time.
The steady-shot build in the VX is really good.
Of course the fisheye option and the sound it automatically records are unbeatable.
And glitches, which can be the only downside to the VX, all depends on the state of your VX. I've been filming with a VX for 6 years now and haven't had any glitch problems ever.
One downside: buying tapes, kinda hard to come by for a good price nowadays.
