Welcome Jordan!
Picking the "next" device is always challenging....
I went from Spinners to VV3s to MVP2.0 to Vamo V6 to iPV Minis to iSticks. Went from EVODs to kayfun clones to Protank 2s to Nautiluses to Kanger Sub Minis & Nanos.
Do you want a "stick" a "tube" or a "box"? Do you want to "plug 'n' play" coil heads or learn to build your own? Do you want a self-contained battery or replaceable batteries? Do you "Tootle Puff" or "Chuck Clouds"?
I spent the better part of 2014 "upgrading" because something newer and shinier kept hitting the market. I've sold off my Spinners, 2 VV3s and 2 MVP2.0s. I run my Vamo at home (it's too bulky for me to carry out and about). I mostly carry my iSticks (50W and 30W) because they're easy to handle, and I almost always have a charge cable with me. iPVs pretty much stay at home because I don't want to carry extra batteries around.
So, "what to get" is very subjective. I LOVE my iSticks. I haven't tried very many tanks, so my opinions are very narrow. The Subtanks are relatively airy draws, especially compared to the Nautilus or the Protank 2. Lots rave about the Lemos and the eLeaf GS Airs. I've just never tried them, but I imagine they're pretty good. Now that I've figured out out to properly build and wick coils for my kayfuns, they're fun (pun intended) again too. I've been building an RDA - that's been pretty amusing, and I'm really thinking about investing in another one....
I've blown this into a major hobby.
If you just want to not smoke cigarettes, I would have to say an iStick 30 (smaller form factor) or iStick 50 (battery life) and a Nautilus would do quite nicely.
