PFoil is a much better PvE FR imo, outside of the lower attack rating which is presumably getting updated in HoW. Best in class impact with Acc. Coils and bottom half of mag does more damage, that thing wrecks faces. Also, it's incredibly useful for Oracle and Atheon phases which is a huge plus to people like me who prioritize VoG over all other content.
Light is completely useless in CE and only stands out for PvP where FRs have experienced a Felwinter extinction event. It's impact is sooo low, maybe it's a personal bias but I can't dig it for PvE.
I just really love the fast charge rate LoTA. Plus the 7 round mag before enhanced battery, crowd control, and hive disruptor. But honestly, I haven't used Praetorian Foil that much so I'm anxious to try it out again. You think Glass Half Full is more useful than crowd control? I'm such an obsessive reloader and I always forget to take advantage of GHF.
