GBBRs are usually less likely to break down than AEGs, it's the mags that usually develop leaks.

AEG's are all TEMPERATURE, GBBRs can't short out in the rain (HPA can be all temps)
GBBRs tend to have better stock range and accuracy, have fewer upgrades & therefore cost way less to upgrade fully, and typically have REALLY good performance in their temp range.
Ease of maintenance, need a gundoc to do anything cool to an AEG, anybody can work on a GBBR, there's almost nothing you can screw up.
AEG's always shoot around the same FPS, GBBRs change muzzle energy based on temperature, weight of ammo, maintenance (dirty bolts reduce fps), and gas used.
GBBR's will perform better with heavier ammo vs an AEG shooting the same relative velocity, since the inital pressure is much higher and allows you to impart more hop to the BB without losing drastic velocity.
EX: an AEG shoots 330fps without hop with a .3, you add hop and now it shoots 270
a GBBR shoots 330fps without hop on a .3, you add hop and the fps may very well increase!
Now you could increase the spring in the AEG to maintain the fps after hop, but that would most likely breach the field limit since most people test guns with the hop off.
AEG mags are dirt cheap, GBBR mags are probably going to cost you as much as or more than the gun.
trigger response....well AEG's have potential to be just as fast, but GBBRs are typically quicker.
Good all season workhorse vs realistic awesomeness

Pro's and cons to both.

One thing i've found about GBB's of any kind (Especially the more loud ones) is that it makes people more willing to stay behind cover when they're being shot by them. When I was attending Operation Keystone Strike 4, some guy was using a Mac11 GBB, and when that thing let rip everyone stuck behind walls and windows, haha.

Other than that, most of the other benefits of GBBR's have been spoken already

I'm not sure if the Gas isn't for new guys is valid anymore.

I've seen new players go a season on a KJW rifle and not be let down. They may have a couple issues but nothing career ending.

I've also seen more than a few players in their first season with an AEG that broke who never returned because they couldn't get it fixed.

There is a pretty big knowledge base around gas guns now and they've developed since the first boom a few years ago.

You can fit an effective gas system in a small package for gas guns. Thats why almost everyone uses gas pistols and small submachine guns. You can't put an effective gearbox in a glock!

It's a question of reliability. Every shot out of my finely tuned AEG is the same and I eat GBBr on the field. Also, mag reloads take about half the time and you don't smell like gas.

Of course, I've hit that point where I'm able to do anything mechanical or electrical to an AEG so my view is a little biased.

GBBr feels way better, though. My M14 is sweet as fuck to fire.

Also, SAW. Enough said.

Polarstar SAW?

I have owned both and built both aeg and gbbr.

Gbbr is my preference but is not better IMO.

Gbbr is more realistic (especially g&p woc) and more fun to operate.

AEG is good for consistency and reliability in cold weather which is why I'd say aeg is better.

Polar star doesn't have blow back so its not a Gbbr :/

I can do anything required to repair or refine an AEG but I don't want to.

If I wanted to play with electric trains or make jewelry then those would be my hobbies.

Quotable lmao

GBBRs and temperature:

MAPP/Pro in propane mags works in colder weather and is less subject to cool down when shooting. CO2 also works in cooler weather. NPAS really helps with consistency.

Daytona then

What he said

I think he meant AEG saws as he was leaning towards aegs are better.
But +1 to what coach said a classic m60 is boss lol, wish all th classics werent so damn pricey these days. We need to get the new as companies to buy the old designs and start makin that shit again.
I always yearn for a YE mp5sd6
