I own both. Both are great hunters and have performed well for me. The Marauder has the benefit of the 10 shot rotary clip, which is great when you need a real fast second shot while hunting, the shrouded barrel which makes it extremely quiet and an outstanding trigger. The Marauder of course also can easily be tuned and fine tweaked to your liking. The Disco is a great little rifle as well. The trigger on mine is pretty decent but quite a few people wind up performing triggers mods to it or buy trigger kits for it which are available, as are simple but efficient power adjusters. My Disco is completely stock and it shoots fantastic. One of the nice things about the disco is that it's so light you can carry it for hours in the field while hunting. As for quality of build,,,, I's say the Marauder has the edge, but the overall quality of my disco is very nice. As for accuracy, my Marauder and Disco are both tack drivers with the right pellets. It's a tough choice no doubt as they are both fine guns. One thing to consider is that the Disco/pump combo gives you everything you need to start shooting as soon as you open the box and it does so for less money than you will pay for just the Marauder. With the Marauder you're going to have to purchase either a pump, around $200 or so bucks depending on what you buy, or purchase scuba tanks, hoses and connections. You didn't way what you want the gun for, paper or hunting, or if you're prepared to spend the extra $ for tanks, hoses and connections. I don't really target shoot, I primarily hunt, so from that perspective my advice for someone just starting out in PCP's for hunting would be to go the Disco route. It'll get you up and shooting right away, give you a great hunting rifle and also give you the opportunity to get experienced and educated on PCP's so you can plan your next PCP purchase :)
