well i have the pharaoh and aeronaut and have used the aeolus (my friend has one)
this is my order
1) Pharaoh
2) Aeronaut
3) Aeolus
bottom airflow always produces better flavor then top airflow, that moves the aeolus to the bottom.
the pharaoh clamp deck style is the best and easiest to build on out of the 3. then the aeolus then the aeronaut, aeronaut is hard to build on but I still prefer the clamp deck to the 3 post design of the aeolus.
neither of the 3 have an chance of leaking really. the aeolus could leak if left on it's side but thats it. Both the pharaoh and aeronaut wont leak at all unless turned complete upside down. even laying on their side it won't leak. Pharaoh is also the cheapest of the 3 for authentics. For clones the 3 would probably cost around the same (20ish) authentic pharaoh is 30-40 bucks, aeronaut is 50-65ish, aeolus is 65-75ish
