Truth is, all of them I've tried can handle not only 70/30, but all VG, which I use. But I mainly use an rta, and use pods for convenience and mobility. And even with an rta, I use .58ohm @ approx 10w, and hit it less than 200 times a day, rarely taking more than 2 consecutive hits. About 2ml/day. So I don't drive them really hard.
I've tried (kind of in order, I think):
Smok Infinix - great hitting pod, but died in about a month.
Juul - pretty light hitting, but so heavy on the nic that it kind of satisfies. I can refill a pod 1 time with my own NET. Works okay, but doesn't come close to an rta type hit.
Vaporesso Renova Zero- nice little unit, but draw activation wasn't sensitive enough. Have to suck really hard to activate, and I like slow draws. Traded it for:
Innokin EQ- Pretty nice unit. Larger than I'd like. Good 2ml (I think?) capacity. Easy to fill. No leaking. Very solid hit that comes close to an rta. I've refilled pods several times - they seem to give better "mileage" (juiceage?) than any pod I've tried. But it's button activated.
HCigar Akso- hands down, my favorite. Small form factor, like a Juul, but slightly larger. Prefilled pods and refillable pods supposed to be available. Came with Ice Mint and Nutty Tobacco prefilled pods - these are OUTSTANDING. Best juice I've ever tasted that I didn't make. But sadly, I can't find them anywhere now. I think there's only one site that sells refillable pods. But HCigar just released the Akso OS. I'm not sure of the difference, but if it's popular, and pods seem readily available, I'll get one.
VooPoo Rota- I won this one. Nice size, draw activated. Has a useless gimmicky fidget spinner function. It was defective out of the box- the two sides weren't fully pressed together, so it let in far too much air. VooPoo never responded to me about it.
Orion Q- my son uses this, and I've tried it several times. Nice vape, but very warm/hot. Expensive pods. Nice unit, but it's not for me.
On my watch list: UWell Caliburn. I really won't be an early adopter anymore after the disappointment of the Akso pod availability. I don't care how great a pod is, I want to make sure it'll be available for a while.
