I still like the gasser for some items. I don't use it much anymore, because while I was laid up in bed with back issues, my Wifey cooked for the first time in the 20 years we have been together. She loved it and it is now "hers"!
Anway, there are some times when I do a marinade or special seasoning, and I want to taste that over the kingsford on the kettle, or lump on the WSM flavor. We do shrimp and scallops on the grill a lot now, and I don't want kingsford flavor in it. Some like that, I don't.
I like the "flame kiss" of the gasser on certain items. If I want some smoke flavor, I use those pellets in the foil.
If I had to get rid of one of my 3 cookers, it would be the gasser though.
