I've owned both rifles in .22 cal .The Talon is much lighter/compact,a bit louder and gives you double the shots before needing a recharge due to a larger airtank.
Marauder is a more conventional looking rifle ,multi shot capable and also very spotty in the accuracy department.If you are lucky you will get an amazinly accurate
sample,if not it will drive you to insanity like myself and lots of others.Sometimes its the older baffles,which Benjamin usualy replaces for free othertimes its next to
imposible to find the cause of all those wild fliers.
To me accuracy is everything so i would not take a chance on a Marauder,would definately go with the Talon.
My two favorite airguns right now are my two Discos in .177/.22 ,yes they are louder but lightweight,dependable,decent looking,inexpensive and most importantly
accurate.
Best of luck with your decision and if you go with the Marauder i hope you get one that shoots,the ones that do ,really shoot very well.
