For 30 years Deere has outsold Case IH with "Inferior" combines.  Strange thing is this is a free country and people can buy whatever they want.  The free market speaks volumes.    I will give you that during late 70's and early 80's IH had a much better combine than Deere-my opinion anyway.  But their dealer support and parts have been so incredibly incredibly behind Deere that now even those machines are a questionable purchase vs a Deere of the same era.  So there is your answer as it relates to me.    You may call them crap but I have a 30 year old Deere with over 5000 hours that has been down less than 5 hours in the last 100+.  Not too bad in my book....and a lot better uptime than I have heard compared to many 8010 owners on the Case forum.
