Tippmann is crazy loud. I used it at Mach1, and it was crazy loud, couldn't shoot randomly to give my position away, so had to make each shot count when hiding in the darker areas.
Co2 mags with the cartridge aren't as consistent as a HPA setup, because when the Co2 starts getting empty, you notice your guns becomes sluggish. You also can't eject the mag since it is punctured and attached to the internal system, once you eject the magazine, that cartridge is done, and requires a new one.
There warranty is great, you can call in and they will ship you replacement parts, easy peasey, no fees.
Gun needs a proper tune to get it going well, but I used it on semi only, so regardless it work quite well for me.
Here's how mine looked during my ownership.

Sold it off for a GHK M4, and never looked back, reason why I sold it - wasn't a fan of having a tank strapped to my back again, been there done that, tried it. Tippmann is a great start for a Daytona gun style platform. Didn't like the proprietary crap, no removable trigger guard, etc.
Also refilling HPA was a nuisance to go out and do it
