In any case, using an active perception check only has about a 50% chance of beating a passive check, so it's not necessarily any more advantageous.
Not entirely accurate.
Sure, you only have roughly a 50/50 chance of rolling higher than your passive perception.
But, for example, when a rogue with +9 Stealth tries to hide from a kobold with +1 Perception, that rogue only needs to roll a 3 to beat the kobold. Every time.
90% of the rogue's rolls will beat the kobold.
But, when the rogue rolls a 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12, the kobold who relies on passive perception will never never never never see the rogue (with these rolls), but if the kobold makes an active Perception roll, there's at least the chance that he could roll high enough to see the rogue.
Sure, that doesn't address the RAW.
All I am pointing out is that your remark that "it's not necessarily any more advantageous" is not entirely accurate.
I would say that having a chance to spot the rogue is greatly advantageous over having no chance at all.
