warning and considering use with an SSV
the sgw i'd recommend over all of the others, but its been sold out almost every online shop for a while
For the price, I don't really recommend a custom ehle or worked (basic beaker) illadelph simply because it doesn't have anything "going for it" besides brand recognition. There's nothing innovative about the diffusion, the glass isn't particularly thick, and the workings are real basic and simple.
The only possibly bad thing about that b. wilson is, sometimes when blowers use single-colored glass sections like that, it can be an outsourced part and subsequently not as quality glass or as thick. In the picture it looks a little thin at the top compared to the top of a totally clear b. wilson tube.
I want to make clear that only SOME blowers do that, and I have no confirmation that is true for b. wilson, but it that is a trend and it looks a little thin to my eyes.
And one thing about the euphoria piece, its an inline tube but it only has 6 slits in that inline. HOPS, the inventor of the inline, makes an inline tube defaulted with 12 slits. And the b. wilson has 11. To me that just shows me he might not be as experienced at making inlines as hops, wilsons, and headford to name the big dogs
I would say if you're spending hundreds you want a lot of function.
You really can't go wrong function-wise with a well made inline, 6arm+, or showerhead diffusions styles. If you want a tube that just has your basic downstem, there's plenty of great choices well under $100-150
Past that basic form decision, which for vapor isn't hugely significant, (and since you're buying from reputable blowers they're all going to be durable), its 100% aesthetic preference.
In case you dont have this source too, for $300 price range SSFG has a handful of tubes and bubblers with great diffusion. In that range showerheads, inlines, stemlines.
