Legendary vs. Legacy

[Hazkali]

I've noticed that Legendary Weapons and Legacy Weapons (from the aptly-named Weapons of Legacy) are very similar, and indeed, the latter probably spawned from the former. My question is, does anyone have an opinion on which is better?

It is not really an answer, but imo both are not very good. Legendary weapons require you to take class levels in them (taking away your class features in exchange for their mostly mediocre abilities) and weapons of legacy do take away some of your primary bonuses (BAB, skill points, saves, HP, spell slots) while often being less powerful than bought weapons, because they cannot be enhanced further.
While both of these (I personally like the weapons of legacy more) are very flavourful if used wisely imo, the mechanics tend to make them a burden instead of a bonus.

P.S. WoL can be useful in low-magic campaigns, but only with restrictions to some abilities
