I have found that I have different tastes for different things. So, I have a stick burner but it's used a few times a year. I have the blackstone that is probably used most often. A primo for most everything else. And I have a Paella setup.
It really depends on what you like to make and cook. I love cooking outside so it's all good.
But I feel like if you buy a used GOOD quality smoker, you can easily get your money back if you don't like it. I feel like a 1500 ASF instantly becomes a 900 smoker on the used market whereas if you'd paid 800 for it, you could get it back out if that makes sense.
I do not own pellet smokers so I don't know what I'm missing. I don't have a gas system anymore but I don't miss the quick fire up or time saving. For me, if I need something cooked fast, I'll make it in a pan or oven. Otherwise, I try to enjoy the cook.
