What's better - 5.9 or 6.7?

What engine do you think is better? The 5.9 or 6.7 engine? I know a lot of guys that will say the 5.9 because it doesn't have all the after-treatment junk the 6.7 does. But there's starting to be a pretty good following with the 6.7 too, despite all the technical hurdles to tuning it. What do you think?  

i would go with the 5.9 due to the fact its a proven motor alltho it seems a lot of guys  are finally having succes with their 6.7 motors  

The 6.7 certainly has a lot of potential, but the exhaust after-treatment equipment is a significant obstacle to performance.  

Depends if you like to play with computers or not. The 6.7 is way more complicated than the 5.9. And which 5.9 are we talking about? 12valve? 24valve? HO?

Bottom line, blowing smoke is like having no teeth, generally doesn't portray the highest level of intelligence

All cummins engines are good....there was one guy who made like 1150 hp out of a 5.9......but there is also another guy on DP that makes like 650 and runs low 3's , 0-60 time in his 6.7....so they are both good for hp, but for reliability go with the 5.9 because there isn't as much electrical junk, its been around for a lond time and, its mostly mechanical...either or they are both good motors  

i would go with the 5.9 cuzz i heard that the 6.7 oil pumps arent strong enough to even be at idle
