I went through this same scenario about 8 years ago. I had a Stump gravity cooker and wanted something even more set and forget so I could go out at 4:00 AM, throw a brisket on, hit a switch, and go have a shower and have a coffee. Then go out and mow fields or something. So I searched hard for a pellet smoker that would actually produce a good smoke flavor that I still could afford/stay married, lol. And isn't that always the, "you get what you paid for", dividing line? What I learned was all pellet smokers are not the same. Like everything else, there are very high-end pellet units for mostly commercial and competition use, a mid-range, and the big box store grade. They can all be engineered a little differently and have different effects and outcomes.
I was willing to spend 2 or 3 grand at the time. From doing exactly what you are doing I asked and searched for answers. On this site and from whoever was responding at the time, the consensus was, at that price range that MAC Grills had a good line of reliable grills that actually put a reasonable amount of smoke flavor on the meat. There were others too but most that guys really raved about were beyond my "cry once" limit. So I bought MAC's One Star General, and I do like it. Being a pellet smoker, it was pretty darn good.
My brother-in-law is a good Q'er too. He has some RecTec model and has to use the smoke tube and swears it puts a good smoke on the meat too. But my wife and I can not find much of a trace of it. Don't get me wrong, he is a very good cook and makes food that is as good as I can make and many times, much better. But the smoke is a very distant profile, if is there at all. But he got the best he could for the money and so did I.
The long and short of it is that there are a lot of different units out there that have different capabilities and price ranges. There are those that really do produce more of a smoke. But there are also diminishing returns. What was right for me at the time was to investigate the heck out of it, settle within my desired price limit, and then go on to find out if there are some pellets that are better than others. It never ends but that is what makes it fun, right??? Good luck and I hope you find what is best for you, whether you end up buying a pellet smoker or not.
