Honestly, I would establish what you want out of your e-cig, different scenarios require different applications.
To me, I wanted something that looked like a cigarette so I could go out to bars and Ihop (where I smoke the most!) and not have to worry about looking awkward. As a relatively new e-smoker…I love my super-mini. I did purchase a DSE901 (the mini cig) and smoke it as well. So here are my pros and cons for a pack-a-day-smoker:
SuperMini: Battery last me about an 8 hour day, I go through about 3 carts, it’s quick and easy and I don’t have to carry around any e-liquid. To me…the supermini is my single choice for going out and when I’m on the go. I do refill them at home…they are little harder but…how hard is it really to refill? The draw is quite a bit harder but the throat hit is good. (It's been 2 1/2 weeks and no need for a replacement atomizer yet)
Price: Around $50...depending on where you get it.
DSE901: Love it, smoke it mostly at home, it’s easy to refill and if I want to draw some attention to myself, I take it out to the bar, the battery last longer and I refill the cartridge about twice a day; very easy to refill since the wool of the cartridge is right on top. The draw is very easy and the throat hit is excellent. (It's been 1 week...no new atomizer yet)
Price: Around $50...depending on where you get it.
So…my two cents…it's all based on where and how often you smoke. If you smoke more than a pack-a-day...I would recommend the mini cig (DSE901)
Hope this helps and goodluck!
