comparing dimensional shingles

Dimensional (aka architectural) shingles are the most popular choice for new roofs today... 20 years ago there was a noticable difference in quality between higher priced dimensional shingles and the lower priced ones. That have changed. I firmly believe that any dimensional shingle today could serve full 30 years, if it is installed properly. Below are the economy lines of dimensional shinge from each manufacturer: 

Atlas ProLam

pros: heavier than GAF Timberline, good adheasion, larger nailing area, "bread and butter" choice

cons: only 5 color choices, no alegie treatment (color protection good for the first few years)
