If you do enough research you'll find negative responses on every roofing system on the market, most of which stems out of personal preferences,
but regional manufacturer plants also contribute to the problem.
Out of the three you mentioned, Malarkey is the one with the more consistent positive comments.
Never installed Malarkey but they have a pretty unique product from what I have seen. One of my suppliers was stocking them for a couple of years but they didn't sell well because they were more expensive. Well I am not sure if Malarkey started at a 40 year (back when 30, 40, 50 meant something) but that's all my supplier stocked. Not many people sell 40's when all the hacks are selling the absolutely cheapest dog chit shingles they can get their hands on.
I've no experience with pabco. I've had the displeasure of installing a few IKO's over the last 6 or 7 years and they wouldn't be my first choice (personal prefrence). LOL Ed and Sly probably know I am trying hard not to say a bad thing about IKO's so as not to slander and get sued. Infer from that what you will.
