In brief: Flonase better
Allegra is an atihistamine and is helpful for itchiness, sneezing and a runny nose, not helpful for congestion.
Flonase, an intranasal steroid covers all these symptoms plus congestion. Head to head studies comparing Flonase to antihistamines, singulair, (montelukast) or sudafed showed that Flonase beat them all. I usually suggest daily Flonase and adding an antihistamine on as needed or supplemental basis.

Nasal steroids should always be no. 1 for the reasons above. Everything else could be considered a "back up" for the nasal steroid.
