I personally have a bit of experience with all of these markers, so I will tell you my opinions!
Proto Rail 11/ Matrix
The Proto Rail is an absolutely killer budget baller gun. It's got great ergonmics (IMO) for the price. It shoots pretty smooth, but the efficieny is not too great. If that really isn't an issue, I would definetely look into this. The trigger isn't amazing for semi auto, but you can easily change it out. Maintenance on this gun is a bit more difficult than some of the other guns you listed, but it's still pretty straight forward.
My overall rating of it is 8/10
Azodin Blitz Evo
I don't really like the Azodin Blitz EVO, it's very loud, kicky, and I've had some quality issues with the gun. It's not a terrible gun, but I think you could do much better for spending a bit more money. The gun isn't amazingly efficient, but it's still pretty good (IMO). The trigger isn't bad, it's better than the Rail trigger. The board in the gun is really old, and there is almost nothing you can do with it without having to send it in to Azodin. Maintenance is pretty easy though which is a plus. My overall rating of it is 6/10
The Extcy is actually a really solid gun. It's pretty tough in my opinion and has a nice weight to it. It's pretty smooth, and just a pretty nice marker. The Extcy looks really simple but performs great. The efficiency is alright on the gun; it could be better but it could be worse. The trigger on the Extcy isn't too bad, but I'm not sure why, but I just don't like how it feels. My friend however loves it. I guess it's really just what you personally like. Maintenance probably isn't too difficult, however I don't own the gun and can't say (my friend let me play with it).
My overall rating is 8/10
Dangerous Power G4
I would just stay away from Dangerous Power guns. They are known for quality issues and can have bolt stick and leaks. I shot one and thought it was alright, smooth but not the best I've seen in that price range. The trigger on it is not fantastic IMO. Efficiency is okay from what I've heard, but I haven't been able to test that. I would choose something other than the G4.
My overall rating is 5/10
If you really had to choose out of all those guns, I would go with either the Proto Rail or the GOG Extcy. Bothe markers are great, and will suit your needs perfectly. If you have a bit more cash, the Invert Mini is also a gun you should look into if the ergos aren't really a problem for you. The mini as pretty smooth shooter while still having decent efficiency. The gun is great for 350 bucks (if I'm not mistaken). Hopefully you pick a gun that suits you!
Sounds like he is in Canadoo, the land of maple syrup and the majestic moose...
