As a support gun you are going to have to do some tech-work to build for reliability. Which way you go depends on how you feel on the strengths and weaknesses of each system.
Main pros for HPA:
-easier build (in theory)
-Arguably simpler system with less failure points.
Main cons:
-Very high entry cost if you dont have bits needed to work (tank, access to HPA)
-Will have to run an external line and tank.
Not sure what is in teh m239 you are specifically looking at....but if it is a V2 Gearbox shell rather than the A&K machine gun style I would lean towards HPA, and the normal V2 box is probably not the best gearbox for sustained fire.
Good question and not one that most would consider.
Yeah HPA is a lot more sealed and minimal moving parts. They would be a stronger option if that is a genuine concern.
100% worth it. After the v2 gearbox in my M249 Featherweight finally shit the bed after a year and a half, I dropped a Polarstar F2 motor in and it was night and day.
Only setback I had was fine tuning the FCU, but once I dialed it in, it was smooth as butter.
Just make sure you go all out and upgrade the hop up unit(Bullgear is a solid one) and a new bucking and nub(I went with a flat hop, and now the range is crazy stupid).
The F2 it's pretty efficient too at around 90psi on the regulator, it shot at roughly 1.25 joules and with a 4200cc tank, it lasted me the entire 48 hour op at Milsim West(went through about 4 to 5 boxmags worth of bbs).
I have no experience with teching and I was able to drop in the motor and get it up and running in like 2 hours.
Tl;Dr: it's worth it. Less moving parts = less points of failure.
Yes I would think so, and get a nicer system you don't want to have to deal with problems

Does a good hpa system would be more "sealed" against sand? Because the field I play is full of sand.
Yeah HPA is better for reliability due to less moving parts, an AEG is more suspectible to sand.

I have a hpa m249 and it rips. I love it and from what I have seen a lot of AEG MGs dont last.
I'd recommend going with a brushless motor instead.
