While I do think the Dcup and Liger are both neat, interesting devices... calling them "best" is kinda messed up... No offense to owners/enthusiasts of either, but man... That is a lot of metal in the airpath.
A simple banger+rig is the cheapest easiest way to get a high-end concentrate consumption device... A nice
@710Coils setup will easily rival (if not best) a Liger/Dcup setup... for a much lower entry price. I am sure Sapphire and Ruby may taste better, but that's a lot of money that you could potentially break in seconds due to thermal shock...
Bangers (whether torched or used with an enail) also have an ALL GLASS VAPOR PATH.
It's almost insulting if you're spending top dollar on high-end concentrates to burn them, or vape them off of metal/a device with metal airpath...
To each their own of course...
The Puffco Peak only gets an exclusion for me due to how easy it is to clean/maintain the vapor path, and how it is mostly all glass. There's maybe 1inch of high-quality platinum silicone, which is currently necessary considering the devices design.
I'm not going to say the Peak is the best or most fair-priced item on the market, but I have had nothing but great experiences with mine, and have retired my enail setup for now (since >6months ago...lol) since upgrading my Peak to a quartz dish.
