Aren't flat xp bonuses added before %? That said yeah it's a leveling bonus, it's not really good otherwise(and even for lvling it's very so so). That's what the enchanter is for though, assuming you roll perfect other stats. I guess that's the point of the item system, even with smart loot and enchanter, getting a 100% perfect item is going to require a lot of luck, you might get a very good item but it still might have a shitty secondary or one stat that didn't roll the max affix and so on.
