Donning my flame suit...
It's tough to beat a 3.7V source and a 1.5Ω dual coil carto
tank or a decent clearo! VV/VWs are terrific for full batt charge life enjoyment. But there's absolutely nuttin' wrong or lacking with da simple matched (VDC & Ω) combo!
If one seeks their next taste/enjoyment level, they must be prepared to spend money, time (experimentation/modifications) and endure disappointments. Many here do not have da money to 'invest', regardless of time available.
Ergo, if your eGo batt and joose
device satisfies more than your VV, guess which one I would recommend! Your taste buds should be da final judge...
