I'm curious who makes the best sub-bolt-beamer between Jolteon or Electabuzz?

Electabuzz has the advantage of having HP-Grass w/ Ice Punch to cover all weaknesses & he gets Cross Chop, but Jolteon has higher speed, sp. attack, & sp. def. Is it really just a matter of personal preference or is there really a noticeable difference in serious play?

Also, I'm curious to hear of anyone whose had luck w/ a Magneton bolt-beamer.

Thanks
