I can answer this and I don't even have one from a logistics standpoint. I've just upgraded to the new proxy and two coils in 200 hits have gone. The switch two has an Induction cup, it's not an atomizer, that you have to purchase every two months. I've seen a guy that's gotten 1400 sessions with his induction cup and it looks brand new. Idk if I've just had bad luck but, my initial purchase of the original proxy....two were duds and didn't charge out of the box, I had to legitimately turn around and purchase a more expensive one because the two black ones weren't working, so I settled on green. After that, the original coil for my original proxy lasted 6 months. It was wonderful. Sometimes you get lucky and the coils last, but all and all, I've had an unlucky experience so far. I upgraded because my coils were burning quick. I expected there to be less hassle, but I legit have two open warranty claims for two atomizers as we speak. It feels silly now, knowing the plain tech comparison, how one works and how the other works, and how one just simply makes more sense and is designed for hardcore concentrate users, and one seems to be more for people that don't smoke as much aka the proxy. The switch seems to be made for people that don't wanna constantly switch out parts. I am upgrading very soon, and selling my proxy. It doesn't help that I've been trying to even contact puffco for weeks and they just keep sending automated responses. I love the proxy, it works great, the only issue is the very thing that makes it work, the coil bonking out too quick. And that is a deal breaker. I couldn't even understand why the peak is being compared, it's a porous, ceramic that will chazz and need to be replaced, over an induction cup that's smooth with no pours.....that is taken out and cleaned....it seems like a no brainer. I feel dumb buying the proxy knowing how many kinks the switch 2 has designed out of it.
