Almost impossible question to answer. My set up is an Oklahoma Joe which I've had for 4 years. I feel like I've got it figured out now, it took a couple years. I had a New Brunsfield for 20 years before that and had the dialed in, so the dial in time was adjusting to the new (more efficient) smoker.
I'm a nut job. No lighter fluid is ever used, I start charcoal with a propane torch. I have a small swinger grill that sits next to the smoker that I use to charcoal down the wood, so no 'raw' wood ever goes in the fire box. I use an assortment of woods, that I source myself and split myself. No powders, chips or anything bought commercially. I'm checking on or tending to the fire every 20-40 minutes.
Few people are interested in that level of commitment and learning. For most people a Traeger is the way to go. Ramp up time is zero, and results are consistent. Anyone who can read and do basic math can operate it effectively, and it's fire and forget for the most part.
I started out with a horizontal smoker, though much cheaper quality than yours. After heavily modifying it, it was halfway decent. But I got tired of the constant firebox tending, pulling all-nighters on briskets and pork butts, etc. I currently have 3 electrics, 1 charcoal, and one pellet pooper; I'm happy with those (for now).
