Part of it depends on your qualifications and aircraft; for instance, one the A-36 and the Baron, Falcon works with ABS and has done very well for me. Also, other owners have given me great perspective. On experimentals, others seem to do much better. AOPA wasn't very competitive for me and my planes; perhaps it's the broker I was in touch with. EAA wouldn't be attractive for my situation either, but fits some of my friends with things like an RV very well.
