Too soon to say, and frankly maybe too many variables that are different... If I can get a basket screen going that might be a fairer comparison, capsule itself is too different I think, aside from the wood stem vs glass being different... but I think the cooling is very effective and it doesn't get as hot to hold as the other two, though the bent insert is much longer too (haven't tried small insert yet) Also in my experience none of them really do that amazing job of cooling vapor, it still feels hot and harsh if you take a big rip, but better than nothing! Theoretically the amaze should help the stem stay cooler during a session, with the nub getting much hotter for me, and short spiky bendy getting hot but having a place to hold it safely near the tip. I have others as well (custom horned long spiky bent, plain long bent stems, the whip, and the mini j hook, I'm a strong advocate for the last two)
