I'm no EE either just a well seasoned vaper who has experimented with many different devices. I'm not a fan of the LR attys because I've found they don't hold up as well and I don't want to be limited to just that type of atty. There is a much larger range of atty/cartomizer options in the standard resistence ones. Plus on some PV models, such as the eGo, LR attys have been known to kill the switch on the PV.
Using a Darwin VV PV, I found that 8.5 watts on an 801 atty or carto with a 3.0 resistence gets me right around 4.8 volts. I like the 4.5 to 5.0 volt range for vaping.
You do have a point about the LR attys, I get about a week out of them myself. But that's one of the reasons I switched to the Boge LR cartos. I get about a day or two less from them, but for under $2 each I can deal with that. Using my P16, I get 6.8 watts with a Boge 2.0 carto. Or 9.1 watts with a LR BE112 at 1.5 ohms. Both right in that "sweet spot" range.
Interestingly enough, the Boge carto produces a warmer vapor than the BE112 even though the wattage is lower... so atty/carto design does come into play as well, it's not just about the watts.
Another factor to consider is size of the device and aesthetics. This is were the 3.7v devices really win out in my opinion.
It really all just depends on exactly what you''re looking for. For straight performance I'd agree that a variable volt device is probably best. But if size, aesthetics, and reliability are a concern, then perhaps a 3.7v mechanical device would be best. Either way, you can get attys or cartos in the ohms to put you right in the "sweet spot" for vaping. It's all about choices, and finding what's best for you.
I do strongly suggest using high drain batteries with LR attys though. There is a noticeable difference in my opinion.
