carfax, autocheck or others Whats good because I need to get one run

I found a Challenger SRT I'm interested in but its in another state other side of the USA to me.  Autocheck states 4 issues and Carfax says 15.  I'll have to purchase one of them to get the details.   I've read the topics pros and cons for Carfax but nothing on auto check.  I want to get a check but is any one better than the other and why so much difference.  Got to run vin and find out something by morning.
