Rather than easier and more difficult, what about more willing to work with thin profiles/previous bad issues.
Cap 1 is usually considered "easy" because they are more forgiving, even if you have burned them in the past. Some are not willing to forgive and/or forget (AMEX might be easy now, but if you burned them in the past, they seem to have a 20 year memory, give or take). Some don't want HPs but will work with a lower score with very few HPs (Chase, Barclay, FNBO). Some don't care how many HPs you have if your income/score will support their U/W. (Synch, PenFed)
But, truly, what worked for me might not work for you, and you might get it with one of my Unicorns. Hence, YMMV.
