While the Kettle and Electropath combo is my favorite ballvape combo (followed closely by TKO), I don't find it quite at the pinnacle of flavor (at least where I have it dialed in). But certainly no slouch, and similarity to Herborizer design is prob helping it out there. But in general, I find all ball vapes I've tried to be about the same for flavor (and still distincy different from other designs in terms of effects, especially the Kettle/Electropath combo). I haven't tried Phase 3, but do have the CC Zirconia Zeal (which I am about revisit side by side with TKO on my dry Laceface Terplock). I expect those to be similar and personally prefer the diffuser style of Zeal to the injector style used by Phase 3 (last I checked their lineup).
But I still find it much superior to some other vapes mentioned here. Especially the Firewoods. Just broke both of mine back out, and while a lovely artisan design, flavor from those heaters and airpaths fall well behind all the halogen vapes I've tried. Just not a heater/chamber material that is very conducive to flavor IME. Overall, I have much less of a niche/use case for them in my collection. Pretty wood, but just sort of a fine all-arounder.
If you are hunting portable flavor and the session style of a Angus Enhanced isn't your thing (or you are worried about "counterfeit" CE logos
), the Bowle is tops for an on demand portable in my book. Tho I haven't tried the TM2 due to concern about internal glass breaking due to drops, and I know it is a forum favorite. I'm setting aside stem vapes like Tempest, Anvil, Dynavap here because a lot there is dependent on how well you keep those clean, relevant to other designs. Of butane vapes in general, I do think the Vapman remains king, tho Sticky Brick-style options can be excellent. Just gotta get your technique down on those SBs and similar butane torch heat intake tube designs, which can affect things pretty drastically IME.
For non-halogen, non-Herborizer desktops, I gotta say logs are way too slept on by folks chasing the greatest new thing. Whether E-Nano XL, Underdogs or Couchlog, they rarely fail to impress on both flavor and ease of use (especially using Underdog metal stems as a straw, which works better than wider diameter stems for me). My first reaction after getting my first log was "what took me so long?"
