Let's get first thing out of the way - it is not cheap. However, what you get in return is quite worth it.
I like charcoals for the sense of ritual, but they are a major hassle to clean up, plus the smell while they are getting ready is not pleasant. XKAH gets you going fast, and it is dead simple to set up. Battery life is decent and power bank charges reasonably fast if you have 40w PD charger. On full charge, you get two 90 minute sessions out of it. I got a spare bank to not worry about the downtime.
It takes a few tries to dial in the temperature settings for the tobacco you like. My range for blond-reds blend ended up being 265-280. It is never harsh unless you go crazy. There are no stray embers falling into the bowl, so taste stays smooth throughout the session. I would say that cloud volume might be slightly lower what I get from coals, but the temps are most likely lower than what I was used to, and I still am adjusting the bowl packing. In my opinion, tradeoff is reasonable as the taste profile is more pleasant.
Clean-up is straightforward. Could be a bit easier if not for the grills in the bowl, but I get why they are there and I did manage to get it clean with just water. Not a downgrade to clay bowl in this regard so far.
Overall, my only complaint so far is the battery capacity. You really need that spare to have peace of mind if you are having a longer session. Controls can also be improved, as I sometimes need to look up the manual to make sure how to do what I want, but that is also matter of habit.
