Infi is not "magic" but it's the absolute best steel i own. I wouldn't trade my TGLB for any other knife of similar design made today.
If you want the most durable hard use knife your money can buy, you want one made of INFI or possibly SR77/SR101... i just don't think a Strider is going to compete with an INFI knife in that category
Again, i think strider makes a VERY good knife, and i think it will do almost anything you'd ever ask a knife to do, but it's not at the same level as a Busse
Strider vs Infi is really more about CPM 3V/S30V vs INFI (assuming you're looking at a large knife), and that's been explored multiple times here on BF
The general consensus is that INFI outperforms 3v in most categories

And S30V gets no love in large fixed blades
