I am often asked which method I use and prefer and I say it doesn't really matter. What matters is that the specialist is truly gifted at sculpting brows and knows how to shape properly using the tools of choice. Anyone can ruin your brows with either method if they aren't particular and gifted at what they do.
If each method is used accurately by a trained professional, then it all comes down to if they can shape properly or not. Tweezing is the most accurate form of hair removal out of everything.
The nature of threading and the common fault I see, seems to make brows thinner and thinner over time. With waxing the common fault I see is rounded brows. There are claims that wax pulling at the skin can age it, but stretching the skin for threading is also pulling at collagen and therefore could also be ageing.
I have never in all my years in the beauty industry ever seen any scientific studies proving either of those claims. Sleeping on our face likely has more stretching on the skin every night then once a month brow maintenance. Some people can react to both threading and waxing, in which case tweezing is only used. Also no waxing above brows before any kind of photo shoot is recommended so as not to affect even makeup application.
