I haven't necessarily hit them side-by-side, as in like the same hitting session, but I have hit quite a bit with both. Also, I really like both racquets a lot. Kind of in relation to the stiffness ratings, but I will start off by mentioning the comfort is a bit better overall with the Radical Pro, as it feels a bit more plush; I like how it feels comfortable and plush but not too flexy, so there is still a nice pop on the ball when hitting my groundstrokes. The TFight ISO 315 is a bit stiffer feeling overall, although the dampening is pretty good so it helps with comfort but still a stiffer feel overall. This stiffness does make for a very solid feel and some nice power. I find it fun and tempting to use the TFight ISO 315, lots of power and spin but also pretty precise. That said, I think in pressure situations, or on those days where I don't feel all that dialed, the Radical Pro gives me a bit more control, and the 16x19 pattern is a bit tighter for a little more feel and control when things are tight and I really have to rely on my placement.
So overall really like them both, but if it was a racquet I had to pick and stick with I might lean slightly towards the Radical Pro Auxetic for a little more trust in it, and better overall arm-comfort.
