Why every car needs a PCV catch can

Here's what was drained from my Camaro and G35, both after about 5-6K miles. Both looked similar but the Camaro had a lot of water too, about as much water as there was oil, while the G didnt have and straight water, just the choco mix and oil.
The Camaro has the Norris can and it is top notch quality. My G35 and Land Cruiser both have ebay cans that I just shoved a brillo pad in to help catch oil and water vapor. They both work the same, just he ebay parts are obviously cheap and I worry about long term reliability, vacuum leaks etc. So both of those will eventually get replaced with quality units. As far as performance, I'm getting more timing advance and the seat of the pants difference is very noticeable in all three vehicles.
Anyways just thought I'd post this in case anyone was wondering if they actually work, which they obviously do, and and if the high price pieces are worth it, which they are.

I just installed a water separater for an air compressor to use a catch can in my grand cherokee. It has so much blow by its coating the inside of the intake so had to try something.

I deleted my entire PCV system and get no oil in my intake or TB..................
I ran a hose from the rear drivers side where the PCV system originated and attached a breather to it and also put a breather on my passenger side valve cover. Been running this way for two years without any issues:

No damage is really done by not having one, just less advance timing (aka less responsiveness) a dirty TB and intake.
Thats a good way to keep the pressure from building up, and keeping all oil out of the intake, but it doesn't force fresh air through the crankcase like the PCV system does. I've heard it can stink and cause toxic fumes but I dont know. To each his own tho, and your engine bay looks awesome!
Here's a pic of my overflow can being drained.
