IMO - sometimes simpler is the better. I love my analog #2 but I am sure that there are many on this forum that love their digital models. Just keep on smoking and enjoying.
I have had them both and they each have their plusses and minuses. the analog temp swings more and depending how much meat you put in, the consistency of time to cook can be different. I track almost every smoke on a spreadsheet with my process, outside temp, temp used and results. I can say this pretty factually.
The Digital holds temp a lot better and helps nail the meal. I find the analog more "craft" than science and that can be fun too. it feels more like a challenge.
I think the analog smokes the meat better due to the swings in the heat up. Meat only accepts smoke until 140 degrees (so i am told here). i think the swings in the analog allow a little more time but that is my uneducated opinion.
I think the kind of personality you have would determine what you like more. I'm a split personality so i like them both
If your en engineer type, you'd like the D. if you more creative, like the challenge you may like the analog more. my opinion only from a year of smoking with each one.
I dont have an overwhelming preference. I will admit I usally prefer simpler
