Ever heard of the term 'Ad hominem'? You're continuously grossly over-exaggerating the downsides of wattage rather than actually describing the benefits of TC. Doesn't make for a very good commentary.
And, that's what we're talking about here. If someone wanted to take 8s pulls and were encountering issues of either overheating/burns towards the end, or an unpleasant ramp up time, then of course TC could very well help. But, the OP is enjoying their vape, has no complaints, and is asking what TC can do for him, and quite frankly, the answer is 'nothing,' TC can lower ramp up time, it can prevent overheating, but that's what it does, it's not some miracle to make your vape hands down better, it just adds more controls to tweak. I have nothing against TC, it certainly has it's benefits, but I'm like the OP in that I have been able to dial in my vape to make it perfect as far as I'm concerned.
As a quick aside, my spell check wants me to change the word "hominem" to "Eminem" apparently it likes rappers more than Latin terms.
