In the first one, I never remember having any problems with anything besides Entei. BUT I to this day have never captured Rayquaza.
In the second one Drapion and Rampardos were easy. Regigigas, Darkrai, and anything in the Arena were hard. Honorable mention goes to Celebi for being nearly impossible to catch up to.
I'm SO SORRY that I've missed nearly the entire past month. Some serious stuff happened, and I'm really sorry to those here who were affected due to it. If I've forgotten anything I was obligated to do, PLEASE PM me.
