[Whatever number] the weapons from PoTD are only usable for level 60, so you wouldn't benefit of them during the leveling anyway. As for end game weapons, they currently hold a good place, not the highest one, but fairly decent 60 weapons. However again, SB is just around the corner and it is bound to give you level appropriate weapons as quest reward so the PoTD weapons will be left behind soon. If you wouldn't get a tangible benefit from them in the meanwhile, consider keeping the score.
