Hi mate, I have never owned a fx2000 so can't comment but, I currently have an airarms s410 classic and I love it! I used to think my logun axsor was the business but after getting the s410, there's no going back for me! I use mine for rabbits, pigeons, tree rats and magpies, and its never let me down once, I quite happily shoot out to 40 yards and its more than enough for me. Good luck mate hope u make the right choice
