I have both, I like both, and frankly from a function standpoint they both work equally well for me. I do like that the Visconti fits in a slot in a pen case for travel, its super convenient and I have never had one leak on me. Having said that, considering it is three times the price of the Pineider, I cannot justify having several. And I kind of feel like it is really a 35$ piece of plastic rather than a $75 dollar piece of plastic. Anyone have any other thoughts?
