This is going to get the whole pot stirred up. Some claim adjustable voltage is better, others adjustable wattage. There are also some like me that run mechanical mods so both are factor that work hand in hand. This isn't about the mechanical mod crowd, but those who stand by there just for voltage or just for wattage mods. If you say one is better than the other than just don't say it give reasons why it is. That wave those who are trying to decide will have the information and opinions to base their purchases off of. I really can't wait to see the results.
