I only have the
sigelei's and I have the V2, the mini and the V3. I chose the
sigelei's after listening to Phil Busardo's YouTube video:

I prefer the V3, the telescoping Sigelei the best. A good video on that model is:

Anyway, can't personally speak to the actual comparison, but I think the videos cover the important points in detail. I prefer the OLED display, and the build quality is very good on the Sigelei. After a few months, and a bunch of mods later, I still prefer the V3 over all other mods at this time, though I do have my eye on a Semovar, my ultimate, currently my finish is out of stock. But I digress. Recommend you check out the videos, and even the ones on the smoktech, then see if you can go to the local vape shop to check them out in person. You cannot replace the feel, the heft, etc. unless you do go check them out. That practice has saved me a lot of disappointment along the way. Anyway, my two cents. Welcome and Vape On!
