Dead Cold Day
I think they both peaked at different times...some of Hetfield's riffs on MOP and Justice are fucking brilliant (and Cliff Burton is a huge reason MOP is as good as it is)...and Mustaine has some great ones on Peace Sells and Rust in Peace...I don't really throw Kirk in there because I think his rhythm playing is a bit weak. James and Dave both kicked major ass in their primes in my opinion...
