There's a lot of banter going on in this thread.

I think the concensus of responses is to use whatever juice delivery device that YOU prefer and get a great vape from. Everyone ends up with one or several devices that they enjoy using, and will recommend that you should try this or that for a better vaping experience. Unless you're in the mood for experimentation, ignore them. Stick with what works for you.
My first mods were mechanical. They gave me what at that time was a great vape. Then I was able to experience what variable voltage could offer, and I got my first Provari. I still used the mechanical mods, but with my new evolving vaping experience I preferred using variable voltage more.
I initially tried dripping atomizers; I didn't care for them then because I likely never learned the proper technique. I found cartotanks more to my liking and vaping expectations, and used those for several months almost exclusively and was perfectly happy with them. I decided to give an RBA tank a try a couple of months ago, and although there was a definite learning curve involved, they are now my preferred at-home juice delivery device. However, I still find my RBAs to be inconsistant and fussy at times, but that's ok because I still have my trusty cartotanks to fall back on. I still use the cartotanks for out-and-about, because the RBAs are not really travel-friendly.
I had planned on wiping the dust off of my mechanical Silver Bullet and using my RBAs on it. After all, everything I had read here was the vape was better with an RBA on a mechanical. Well guess what? I prefer the RBAs on the Provari's. I still want the option to adjust the voltage for the juice and my mood at the time, and I can't do that with the RBA on a mechanical mod, now can I?
Some of my buddies here on ECF have been singing the praises of bottom feeding box mods. I had never tried one before, so my curiousity got the best of me. I got an inexpensive VMod and am learning the delicate techique of "sqonking" the bottom feeder. It's an enjoyable vape and a nice on-the-go PV.
Mechanicals, variable voltage APVs, bottom feeding APV's all have their place, as do all of the various juice delivery devices. If you feel like exploring the possibilities from time to time as I do, take the plunge. But don't ever feel "pressured" to do so, do it when YOU are ready for change.
