Is Opensiteexplorer.org missing a lot of backlink data?

[RonMedlin]

I was checking a few of my clients backlinks that recently got hit by the "penguin" update to possibly try and remove some of the potentially spammy links.

I ran reports in both opensiteexplorer.org and majesticseo and majesticseo brings back a ton more links, and these are sites that don't even have the max 10,000 backlinks that OSE should be bringing back.  Does OSE bring back reliable backlink data?  I'm starting to wonder.

OSE is not set up to show every possible link. It is showing the more relevant/significant links and most state that it shows about a fourth of the total. So, the question re: reliable, is yes it is reliable; the links shown are there and the PA/DA, anchor text, etc. are accurate. What it will not show is every link. 
Also, it won't show newer links but if you look after a recent update is published and a link is not there, look again after the next and you should see the newer link.
