Hi, Air1,
OK,
Stone II vs. Grande:
Grande has four wicks so has no problems with wicking, and hits, as they say, "like a freight train". It has very good taste. It's pretty trouble free in that you don't have to mod it to get it to work. No dry hits, and no leaking that I've seen, personally or reported on this forum.
It has a really tight, massive top seal, so taking it out to clean and then putting it back in has to be done carefully. You have to keep it on the batt lest you push the center pin through the bottom, since you have to apply some downward force to the seal to put it back in place.
I haven't actually cleaned it yet, but people have reported that it's not problematic.
It comes in at about 2.8, 2.9 Ohms. I can vape it with 100% VG
juice at 5V back to back - no problems whatsoever, great wicking, great taste. Other than because it hits so hard it gives me coughing fits. I usually vape it at 3.7 for that reason - no need to aggravate my asthma.
I haven't seen any negative
reviews so far for this critter.
Vision II has slightly larger capacity, I think, but not by much. It has standard CE2 (Visions Extreme) innards. People have reported some problems with occasional dry hits and flooding, as well as (fairly rare in this version) leaking. These things seem to be pretty easily fixed with simple modding. See this video:

The taste is apparently a bit more muted than the Grande.
This tank is very easy to take apart, since both top and bottom simply screw onto the tube. It has good potential for being truly modular. GV will have replaceable innards arriving at some point.
Some people love the Stone some not so much. According to GV there will be further improvements. It looks really, really nice, and it does have the coolness factor going for it, definitely.
I personally know that when it works, it works wonderfully well. I haven't had to do any mods on it.
Fluxomizer vs. Vision Extreme:
Fluxos have really good taste. They have very high quality tubes that can be easily removed from the carto for cleaning purposes. Cleaning is very easy. These things never leak and live forever.
You have to do a simple mod to avoid dry hits with the XL size. There is a vid somewhere, but basically you replace the cup seal with the middle O-ring ridged side down, and fluff the wicks.
With the Reg. sized one, you really don't have to do anything by and large. At least I don't. I do it anyways, just to be on the safe side though.
There is a modding kit for Fluxos available on the site that replaces all the seals with the Visions style seal. These work really well, IMO. They make the Fluxo easier to fill, and, to me, improve the taste further.
Fluxos are a tad fatter than a regular carto, so if you like using cones with your eGo, you need to get a special one. I think it's available on the site now.
Vision Extremes generally have absolutely no problem with wicking. They are as close to "just work out of the box" CE2 type carto as you are going to get right now. The only thing that just about matches them for ease of use is the Stardust (that's a whole different story - great carto, that).
Though the tube is glued, I believe, and you can't easily take it off, they are easy to clean and can be dry burned as they are.
The taste is slightly more muted, I think, then with the Fluxo, but they produce a bit more vapor as compared to a minimally modded Fluxo.
I personally tried all sizes but the Giant, and they all work equally well, more or less. My favorite ones are Regulars, Stretches, and Nanos. The latter two seem to give more intense flavor. All three of these you can vape down to the bottom without even needing to tilt.
These very rarely, if ever, leak.
They come in different thicknesses. The Stretch and the Nano are exactly the same width as a regular 510 stick. The Regular is considerably fatter than a Fluxo. The Mini is even fatter than that. The latter two, and the Giant, will require special cones.
These are both very good. I, personally, prefer the Visions, but many people prefer the Fluxos. You really should try them both and see which suits you best.
