YES..... You will see; some will cook hot and fast, others will cook low and slow, some will wrap with foil, some will wrap with butcher paper, and some won't wrap at all. Some smokers burn all wood, others smokers burn charcoal with wood chunks, and other smokers are propane or electric smokers. Some are horizontal, some are vertical, while some are insulated and others are not. It's really a matter of finding the smoker that fits your needs, and then finding the optimal performance that your smoker to produce perfect food.
I bought my Thermapen long before they made the MK4, so I have the classic. I thought about upgrading, but realistically the classic will work fine for me until the day I die.
Think of your tools as any craftsman would have tools. Take pride in them and care for them because they are essential to your end result.
And in the end, it still all boils down to your individual need; what do you need and what will you actually use.
