Ratchet and Clank:Tools of Destruction or Size Matters?

Hey people,I'm asking the people who have played both,which should I get? I played Size Matters before and loved it but I forget everything in it as its been over 2 years now...have never played Tools of Destruction but it seems to have good reviews..I have played R&C 1,R&C Gladiator (or Deadlock for NA) and R&C (Future) A Crack in Time..my favourite seems to be the first R&C but a Crack in Time comes pretty close..in your opinion, which is better? Tools of destruction? or Size Matter and why?
