I think if you chose either cam you would significantly increase the number of dollars you've spent on the motor which is where the upgrade will be most noticeable. at least with a thinner wallet, your butt dyno will be lower in the seat and you might be able to feel a difference.
in all seriousness, you should take all future funds you plan on spending and save for a dual overhead cam 2rz/3rz and never look back. i feel like I am pleading with a gambling addict who thinks if he keeps spending more he will win
Then again, it was a 22R-E and an old 22R that were in Moab if that has any bearing on this discussion about which engine is the best...
Maybe when Gnarls has his 2nd or 3rd midlife crisis he will springs for a V6 Camaro or Mustang and then get some bolt-on upgrades for performance...
