You think he easily beats a fully controlled scarab? Who can read into Quasar more and has obtained knowledge throughout the universe, and can find weak points or strategic wins? Not saying Quasar wouldn't win. Just some insight.
1st, excellent choice of match-up. 2nd, both are awesome characters. 3rd, I'm giving my vote to Quasar simply because I feel his abilities surpass Blue Beetle's in terms of versatility. *Edit* Although, Blue Beetle has the better suit. =P

Quasar , or rather any protector of the universe) has ties with the guardian of quantum band, which happens to be a virtually all knowing cosmic being called Epoch. Quasar is known to ask Epoch various question and she normally answers.
So the bolded part Quasar can do as well, and actually has done a couple of time (normally before the fight as opposed to during one)
Just a generic example of Quasar getting help from Epoch
