Don't have time to add too much, but here is a little info on the VXC vs. some of its biggest competitors.
With almost every vape i have/had stirring is needed to help break up plant matter and expose more surface area to vaporizing temp. After much testing with the VXC, IMO you need one good stir for one good size bowl. This vape could/can be used without stirring whatsoever in small bowls loads but the bigger ones i do see increase in taste and vapor production after the stir. Sometimes i stir twice on a fully packed down can't get any more herb in bowl pack, but i think mostly out of habit.
The VHW and LSV need constant stirring. This is not a huge issue for me in theory, but i HATE how the screen can often come dislodged during stirring. This happens very often to me with the LSV, and sometimes with the VHW branded bowls, and all the damn time with BM bowls for the VHW. What i hate about this most, is i get little vaporized particles stuck in tree perks and other hard to clean places in my glass. It is annoying as hell.
With the VXC EZ load design, no worries. Stir hard and quick, no issue spinning a screen on its side with a poke and letting herb fall down where it shouldn't go. So although stirring is not nearly as necessary as the vast majority of other vapes, when you do need to stir it is quicker, easier, cleaner.
There is also something to be said about the VXC and VHW in that air in the vapor path never touches the heating element like in the LSV, and MW. IMO this produces tastier less hot and harsh vapor. It just seems to be of better quality in the VHW/VXC.
The VXC is the least restricted as far as air flow of the three vapes. the LSV does a decent job in this, but not as easy to pull through as the VXC and as said above air never touches the HE. The VHW is pretty restricted, and this can cause some first time user problems, and takes away from the overall experience IMO.
I would much prefer the LSV and the VHW also had an on and off switch. I basically hate not having any hash marks on the LSV. I am the guy who can't read a watch that has no numbers and indicators. I hated watches that just had hands, no numbers or markers, i never knew what damn time it was. The LSV is the same way. Typically, when turning on the LSV or VHW i pump them up all the way for 10 or 15 minutes, than dial back to vape temp. Lack of hash marks or any sort of indicator of what position the dial is on in the LSV annoys the hell out of me. A tiny tweek in the dial makes a big difference, and i always have a hard time dialing back to the V spot during my first bowl. I have to start low, and dial up a hair at a time. Doable, but annoying.
The VXC heats quicker, and you could leave the unit at your favorite temp, and just turn on and off (no need to change temps during a session like most other vapes). That said, people will sometimes still want to pump it up and VX should have hash marks or indicators of some sort on the final version. (Haven't asked recently, but it was an area i insisted SM look into improving, i used a sharpie marker to draw a little dot on my beta unit in the V spot)
The above is some of the smaller issues and improvements i have seen over the competition on the VXC. This does not include vapor thickness, overall package, ease of use, ect. I have already made plenty of posts about that previously.... Happy waiting fellas, im in the same boat as the rest of you currently, as i no longer have the original zero unit, AKA Old Faithful in the lineup...
LSV is the current daily driver, as i sold my VHW. Believe me when i say, all other vapes seem less appealing when the VXC is in the lineup. Or at the very least, all other water tool based vapes. I know the Solo and PD will always have use regardless, although my PD's have been fading from view. I am expecting a constant place for the Oracle and newest EV1 also.
