Ive never had a problem my Key CD was a Crystal Method Vegas on my 5442 and it was cracked stepped on ect and still took it.
My one issue i ever had with an eclipse was i was Installing one in a Tahoe and i connected it then set evertyhign key cd and such. then Disconnected teh battery for like 35mins came back and it never asked for the CD. Just turned on like it never lost power.
I haved talked to them once or twice for customers but every customer service is ass clowns! Kenwood is the worst i think. hes like did you hook up the constant to the amp? My Exact words "I'm a MECP First class installer and have been installing for over 5 years. YOUR amp is bad!" NO sir its brand new it can't be try again and call after one as we are on lunch between 12 and 1 and its like 11:58.
I could Rant on 99% of car audio companies but that how bussinesses are run. Cerwin Vega was horrbile about 2 years ago. YOu would ship somehting back and not see it for months. Then you would all of a sudden have like 50 brand new speakers in one shipment like WTF is this [censored]!
I would get either one of your choices they both seem very good. SQ is probably better on the Eclipse but i highly doubt you will noice anything. Go with which one you think fits you better. my next deck will probably be a alpine. I've had my Pioneer AVH-6500 for almost a week now. It gets annoying that i can't watch movies. Maybe i just need new toys or something.
