carpedebass ~ ok, well let's see...
taste, throat hit, and vapor are the most important. An easy draw is also important. I really like my style of the vEppo510. The style of my Smoke51 Trio is okay. BTW, what's "TH"?
Looks like MadJack answered your question. So my recommendation would be to get away from the small, analog looking pen style things. I assume you want function over style. The eGo (or clones such as the Riva, etc) are fatter batteries, but perform MUCH better than the small, analog looking things. The rule of thumb is that the more your PV resembles an analog, the worse it will perform.
I'd say go with a solid 510 threaded platform like the eGo or it's many, many clones for your everyday vape. The higher the mAh number (650, 1000, etc) generally means the longer the battery will perform between charging. So, go with the largest mAh battery you can handle until it just gets too large (physically) for your liking.
The reason I say stick with a 510 thread is that it is likely the best platform for being able to try many accessories with the batts. Lots of folks here love the Boge cartos, so you'll want to try those. Also the eGo Mega Dual Coil Cartos and Fluxomizers would be serious contenders for ya'!
