I don't think either of those comparisons works. I've never tried a VHW, but it's gotta be somewhere between the LSV and Cloud at best, so how much better could it be compared to the LSV? What I didn't like about the VHW was the price after I started adding all the accessories I wanted. The only accessory for the LSV that is not included is a WPA, and often times the vendor will throw that in as well.
It just seems so damn fragile. The VHW was suggested to me at the time I was looking for a new vaporizer, before I bought my LSV. I probably would have purchased it if not for its fragility. The LSV is definitely more stout and easier to repair of something goes awry. For two vaporizers at the same price that basically do the same thing, the LSV won, hands down, for me. It's been yanked off the coffee table a half dozen times with no issue. Granted, it fell onto carpet, but I just don't think the VHW would have survived.
The VHW has a 99% glass airpath with electronic temperature control, and having owned both it and the LSV, it blows the LSV out of the water as far as purity is concerned. It was really a Cloud before there was a Cloud, in the sense it gave us a pure airpath with regulated heat, and not a glass cover jammed over a stick heater with a dimmer switch, ala the LSV. My VHW has survived precisely one drop from a 4 foot table onto carpet without incident, but I definitely wouldn't drop it again. That having been said, it has operated for several hundred hours without any issues at all, and that's just during my ownership.
I love the VHW. I wish I bought it as my first home vape, instead of going through so many different Vaporizers, including the DBV and LSV, which were basically just lateral movements. before finally splurging on the VHW. Someday I would like a Cloud, but right now I'm perfectly content with the flavor and excellent vapor density of the VHW.
Sticks, you do have a excellent point about the price of accessories, as the full bowl setup costs I think in excess of $50 or $60 bucks. I got mine used and that definitely made things easier, but all the same I prefer to use a large, funnel-style bowl which I find works better for my purposes, the type you could pick up at any headshop for $10 or $20.
