I have a couple 3.0's and some spinners. I use them when I want something light in the pocket instead of a heavy mod. Performance wise are basically identical because they are just batteries. I like the resistance and vw features on the 3.0 alot but they aren't a must have. It's just as easy to dial the voltage to get the same vape using fixed watts.
I will say that I dropped one of my 3.0's and it screwed up the electronics. Gibberish on the screen and won't fire. Can't be fixed. I don't think they are fragile but definitely not as durable as a spinner IMO because of this.
The 800mah in the 3.0 is no big deal at all. Who doesn't have a mini usb cord within arms reach almost everywhere? They last 4-8 hours (or more) depending on how much you vape. I've never had an issue with the lower mah's. It's nice that the 3.0 tells you when the battery is getting low by changing the color of the fire button. My spinners surprise me often with the flashing light of death.
I think the extra $10 is worth the extra features like vw, resistance, usb charger, and battery indicator. Owning both is a really good answer as well. Odds are high you'll end up with a mod where you can just switch out batteries.
