I have had the vibe for about 9 months now, but can't compare it to any others as its my first pump. Agree with all the previous posts, and particularly like the easybg and easycarb functions for taking all the thought out of bolusing for eating carbs and corrections. The customer service teams are incredibly helpful, and I cannot fault them.
I use the Dexcom, and this means I no longer need to carry the dexcom receiver as it is fully integrated. If I was forced to find a negative, I think the only thing I can come up with is I am slightly disappointed that the screen is a little smaller than the dexcom receiver, but you can still see everything you need, and it is a fair trade off to keep the pump small.
I also like the fact you can customize it with skins purchased online, if that's your thing!
I personally would have the Vibe again, without hesitation
