Lifting Strength
Being generous the Deathclaw is at least three times stronger. If not even more because it can throw a 1.5 ton object a good distance away from itself

- A Deathclaw can punch through BoS Power Armor, which can withstand energy beams that can vaporize humans/animals, have bulletproof eye shields rated to easily block high caliber pistol ammunition, can withstand explosives without heavy risk to the wearer and the worst suits in the franchise still allow soldiers enough durability to take on engagements with Chinese Forces with minimal risk to their life outside of heavy explosives or esoteric weapons. They can also cut through Super Mutant skin which can withstand hundreds of rounds of various ammunition types pumped into it without killing the Super Mutant in question
- A future predator is stronger than lions and can kill people in body armor
Overall the Deathclaw's attack power outstrips the Future Predator's power unless I'm missing something
Speed
Future Predator is faster, but I don't think its fast enough to speed blitz or dodge everything. But it is a nice advantage to have.
Stealth
Deathclaw's hearing and smell are so good that they can track people who or are more or less completely invisible.
Overall I'm giving this to the Deathclaw unless I'm missing something. It outstats the Future Predator in every relevant area and counters the areas it doesn't.
