The ROG strix is positioned higher on the list from ASUS, however the TUF feels beefier and "better made".
if you look default BOOST clock is the EXACT same.
The STIX does have two PWM fan connectors and more lights.
Also be aware both cards are pretty large.
I have the 4070TI ROG STRIX NON OC (not worth the 100 bucks IMHO), and its a great card at 1440P. Lights are PRETTY (if that is your thing).
I had a 6700XT TUF (and that thing just felt like a TANK!!)
Can't go wrong with either one and if the price is the same I would personally go STRIX
STRIX cards comes with a button for OC or Quieter mode.
