I allowed my AFAA to lapse because I had a hard time getting CEUs from them. Since they require at least one course from AFAA as part of the renewal, and AFAA never travelled to my area, I had to do their online training in order to renew, and I wasn’t super-happy with the online training I purchased. So I held the cert for 7 years (one late renewal, so I only count 7 years of the 8 year period) and gave it up.
I’ve been very happy with ACE. Easier to get renewal credits.
