Never compare FFXI relics to FFXIV relics.
FFXIV relics are usually BiS marginally, that maybe gives you a ~1-2% edge against the next best build with final raid tier weapon builds. FFXIV relics are a timesink but slowly but surely reward you with an awesoe weapon, as compared to a final raid tier weapon which could be achieved in less or comparably less time if you practice raiding every day.
FFXI relics/mythics were HUGELY powerful, sometimes exponentially increasing the damage output of the job, fundamentally changed its gameplay/build entirely around it (SAM, DRG, WHM mythics; THF, DRK, BRD, PLD (shield) relics; BRD, BLU. NIN, MNK empyrean (before when those empy WS were locked to the weapons). FFXI relics had no parallel or sidegrade comparable to FFXIV sidegrades of similar ilvl final weapons (Dreadwyrm, Augmented Ironworks, Alexandrian Metal, Augmented Shire). Maybe Hagun was sort of better/worse than Amano, but mythic shat all over both, hugely.
FFXIV 1.0 relics were similar to FFXI relics, but those unique stats were eliminated in ARR, sadly.
