Hi and welcome. All of them will work in the tank. A Smok Osub-- even the 80 watt version-- will struggle trying to fire one of the Octocoils. That's a lot of wire to heat in a hurry with 80 watts. Allow me to suggest you buy one or two of the quads and vape them comparatively against the dual you have. You will like one or the other better, of course, but let's say I won't be shocked if it turns out to be the dualie. You'll have better ramp time with duals if nothing else.
