Bonuses are personal. If you have a 1000 Atk Axe in your Grid, then Herc/Arthur/Axe-preferring Hime will gain 1200 Atk from it, due to the 20% bonus stats.

Also, same-element Eidolons give 10%.

If you look at somebody's profile, you see their Soul's stats. Souls have two preferred weapons (except Dartagnan), so that stat tends to be slightly bloated.

Still, extreme values are only reached by whales. FLB Hime weapons have higher stats than Event weapons, and Kaisers are WAY higher stats than Event Eidolons.
