As it stands today, which company has better QC? I’m thinking of either picking up a Textreme Tour 95 or Pro Staff 97.
Prince, easily. While not as good as Yonex QC, where racquets consistently come at +/- 2g from specs, it's still a darn sight better than Wilson QC, coming anywhere at +/- 10g, sometimes more. But then again, Wilson has got to be the worse of any major brands. I bought 2 PS 97 3 years ago, before I had done any research in racquets, coming back from a long playing hiatus. They were 10g and almost 1cm balance different from each other. Considering that their price is on the higher end of the market, I will never, ever buy any Wilson again until they substantially improve their QC. I am not holding my breath that they will...
I purchased quite a few Prince Phantom's from TW EU (US won't ship to the country I live), and asked for a matching service 3 times. Most of the frames they weighted for me were within -3g / +1g, with just one outlier at +5g. To echo what Yamin was writing above, they tend to generally come a bit lighter than specs. Balance was always within 1mm.
In any event, if you care about specs, I would highly recommend getting the matching service. 10 dollars is not much to avoid the aggravation of having dissimilar racquets.
