Not really. What the OVA has covered of the manga so far, it's done a particularly epic job. It's more entertaining to watch the OVA than to read the manga, for the ~5 volumes it's covered so far.
If it keeps going at this rate of epic, the OVA will be a masterpiece at least equal to the manga.
But sadly, I suspect there's just no way the OVA will ever finish. It's horribly over-deadline, over-budget, and moving along at a snails pace.
