When it comes to getting that analog-like vape, it's all about the volts IMO.
I have both the screwdriver and the GG and they are both very good e-cigs. It just depends on what your needs are.
I used the screwdriver for a few months and I felt like something was still missing.
I use the GG all the time now running at 6 volts. It totally satisfies me with a real analog-like vape.
You can vape with 901 attys, 801 attys, and 510 attys. The 801 attys and 510 attys need an adapter that can be purchased separately.
I did run through a few 901 attys with the GG before I found a few that could take the 6 volts.
But I primarily vape with the 510 atty for a very nice smooth vape. Lots of warm vapor, more vapor, and an awesome throat hit.
When I want to kick it up a notch in warmth and throat hit, I vape with the 901 atty.
I am so tired of the peeps that say with higher volts you get a burnt taste and burnt attys. Someone started this myth and others perpetuate it. If this were true, e-cigs like the Prodigy, the GG, and the Zi Moshi wouldn't be so popular and needed.
Finding the right 901 atty that can take the higher volts might be a consideration, but when you find one that works you'll be in absolute vaping heaven!
For a smoother vape at higher volts though, I would recommend the 510 atty. I've not lost any 510 attys this past month using it with 6 volts. In fact, I've been alternating 2 of them and they are both still working great.
So, if you want to kick it up I would definitely recommend the GG. Lots of warm vapor, more vapor, enhanced flavor and a throat hit that will knock your socks off!
