It's a matter of personal preference.
I would never use anything but the Wisecos. I have seen far too many ST crack at the valve reliefs. My Wisceos have endured 5 seasons, that's roughly 20 hours of operation in competition and have never skipped a beat.
But my car isn't a 300hp street car. And it does sound like a diesel when it's warming up. I don't use the temp gauge to watch it warm up.......I use the vacuum gauge

I live in the northeast but it’s not a daily driver, far from it. Sees 3000-5000 choice miles per year, typically between April and end of October, with a few start-ups during the warmer winter days.
I can see why someone would want to run the supertechs more, I often kick myself for not doing so, but the Wiseco have been good for the last 9,000 miles. Next time I pull the engine apart to do maintenance like rings and bearings, I’ll evaluate. My engine is built pretty loose too, I believe P2W is .0035-.004 (maybe my decimals are off) and bearings are .002 (again pardon my decimals)
