It's the best I've found, for me. There are a lot of coil options but I've pretty much settled on the ceramic donuts. I don't like exposed coils, and didn't care for the buckets, but I really like the donuts.
Not everyone likes the donuts although most agree they taste the best. The knocks are they need to be clean to get that great taste, and they don't provide gigantic lung buster hits, like the metal coils do.
I dirty up a coil a day using it by myself. I load it twice, then put on a clean coil. And when I have several dirty coils, I clean them. I just ordered a five pack today in fact.
Cleaning isn't terribly hard to do. I use a paper towel to wipe out a warm bowl. And my own little trick is to put a couple drops of ro water in the bowl, and boil it a few seconds. That loosens up the reclaim and makes it easier to clean with that towel. I scrunch up some towel into roughly the shape of the bowl and insert and twist it. Then I crank the temp up to 490 and heat up the donut. That dries it out and burns carbon off the donut. It gets red hot. And the donut turns white again. That's bout it. If they seem extra dirty ill soak them in warmed up iso, for a few minutes, and rinse and wipe before the water deal.
The buckets I thought I'd like I did not care for. I tasted ti in the ti bucket and the quartz bucket leaked rosin all over. I never got the taste dialed in either. Best I did was small loads killed in a couple hits. The donuts I can sip on, maintaining great taste, although a few sips and your zonked. the buckets were easy to clean tho, water and a q tip, presto, clean. I'm using 16 w in temp mode at 290F. I get vapor in four or five seconds after I hit the fire button. Less if it's warm.
I'm waiting for a sic bucket with an embedded wire heating it. First one of those out will make someone rich.
