There are ways to get "smokier" with lots of things. It's not always smoke amount but there is a different flavor if that makes sense.I have a new Treager model, timberline I believe, anyway it has a super smoke option when smoking under 225*, puts a nice layer of smoke on the brisket. Or whatever you put on. Just low temp it for a while and get the smoke rolling over the meat, then finish it off.
No complaints, I am sure it could be done smokier, but as said above, who has the time for babysitting it all day long.
Example on my little offset to keep things equal. I get much different smoke flavor if I use charcoal bricketts vs lump charcoal (different brands change again) vs just good quality wood and on the charcoal I supplement with wood. Brickettes normally don't offer much flavor but lump can give off flavor depending on what it is especially if you don’t pre-light it and use your coal bed to get it going. With straight wood higher moisture content will act different with a lower content and in my opinion can give a different flavor all things being equal, cleaner burn vs dirtier burn.
It is more of a hands on hobby depending on how you want to do it. I enjoy playing with the fire and tinkering to control my temps, the resulting food is the payoff. These days I have less time so I use the pellet grill mostly but looking at building an offset myself to mess around with again
