I have only seen a Marauder, not shot one side by side with my Evanix Blizzard. I have shot side by side with an Air Arms 410s. I will take my Blizzard. More power, just as accurate(I shooting mine, the friend shooting his 410) stock on the Blizzard a bit nicer and the finish about the same. Good accuracy with the Blizzard. I get 40 solid shots before having to pump it up. Could probably go more but I don't want to have to do TOO much pumping at one time.
It likes 21-3- grain pellets better than 18 and less, at least mine does and from what others have said this seems to be standard. One of these days I will get a Chrony and work on adjusting it up and down and see how well that works for me.
All I know is it is accurate, looks and feels very nice, is not heavy and shoots well. After I get access to a Marauder in .22 I will do a comparison. That won't be too soon unless someone happens by or I find someone nearby.
It is one nice air rifle and I did take down a coyote with one shot, through the left eye right at 40 yards which is the sweeet spot I have it sighted in at. All conditions were nearly perfece for the shot so that helped a lot. Just like I was shooting at a target or fencepost sighting it in. Then I missed pigeons on top of the barn later... so having time to relax as the coyote worked his way in closer helped. Wish it would happen more often.
