I hate EQ they're about 40 points below my other scores as far as I know. They're super slow updating everything for me. They may show different accounts, or if you've recently paid down your Utl it may not have posted with them yet - there are lots of reasons for differences.
I've got a 40 point difference now with EQ declining (still???) and TU and EX steadily going up
so I might be right there by your side soon.
I'd say your best bet is to compare the accounts on each report and see if you can find any big differences.
Start 2/2008: TU 495 || EX 539 || EQ 528
Now 5/2013: TU 716 || EX ??? || EQ 702
