Reliability of new 2015 6.7 powerstroke or Cummins Diesel

Y'all, there's alot to be said for the older iron. It's not bad and in some cases like OBS Powerstrokes, 7.3 Super dutys and 12V Dodges, it's pretty dang good. I could say the same for GMT400 trucks (minus the 6.5 turdbo diesel...).

BUT, if those touting the old trucks (I got one myself, last 5.9 diesel, 6 speed, tuned to kick some @ss) cant or won't recognize that the new iron is more powerful (stock), safer, more comfortable and more heavy duty all around, then your opinion is not really valid.
