Good luck on your choice. I am in almost exact position. Upgrading from
Masterbuilt electric to a pellet. I also have a Weber Genesis gas and 22 Kettle. I have the usual suspects on my list, CC WW (24), RT (590), and Grilla. Having heckuva time deciding.
With the Weber gas I really don't need the CC Sear/Sidekick so that knocks it down a bit in my eyes.
For RT I don't like the venting on the 590 which makes it difficult to cover in winter. Their internet presence (videos and such) are kinda a slight turn off as I really like to learn from that stuff. Lots of rah rah but not much info.
Grilla just has a smaller presence overall but seems to build a good unit.
Decisions, decisions. Think I'd pick the one that does the best job flat-out smoking but that's hard to quantify.
