I love both of these exercisers.
A ton of people complained that they could not trigger the vibrations for the Vr1. This was not the case for me. It made me work harder because of the anticipation of that exciting vibration. For me, it did exactly what it was supposed to do. However, this is not my go-to kegel set because when I wear sets, I wear them all day. I can't do that with the Vr1 or every one around me would know what is going on down there because it is a bit loud. While it is a brilliant exerciser, I can't say it's the most practical.
The Noir, another favorite, is in my top 3. It's a good option if you want to try the Lelo beads. It's the equivalent the the heaviest weight in the classic and mini, so you get the most weight for the least money and they look the coolest. BUT, while they are heavier, they are less rumbly than the classic and mini because the inner bead is bigger and has a thicker case of rubber.
SO, if you need that rumble factor(like I do) because you have no trouble keeping them in, go with the Luna Beads mini or classic. The classic set is the rumbliest out of the three.
As a first timer, I'd get the Mini and Classic. If you absolutely have to choose between the two, I'd go with the classic. If money is a factor, go with Noir.
Sorry for the epic comment. I am a kegel exerciser connoisseur!
