Both excellent hunting rifles. If your looking for a a backyard friendly gun right out of the box Galation QE is the way to go.1- Side lever action is better for bench or tripod/bipod shooting2- As stated above you can buy an extra air-tube giving you more shots in the field or anywhere without carrying a tank.3- Galation can be regulated down the road. Regulator will give you more consistent shots.4- A ton of tuning info on Hatsans5 - I never shot the Galation but the Hatsan trigger will be lighter and IMO better out of the box. 6 - Galation is heavier in the standard and carbine. 7 - QE edition will be longer compared to the Sumatra carbine Sumatra. 1- If your looking for a lightweight hunting gun the Sumatra. 2- Sumatra has more FPE out of the box and will shoot heavier hunting bullets more accurately.3- Adjustable power by turning a knob4- Will not be pellet fussy and will shoot many pellets accurately. Say Benjamin 25's at Walmart or an online store has a sale on a 25's most likely the Sumatra will shoot it accurately.5- Not backyard friendly. It will cost if you want it to be BYF.($100 - $125) 6- Sumatra looks nicer in person than in photos(JMO)7- Less info on you-tube or online for tuning the Sumatra. Once tuned the longer 2500 is easily a 100+ FPE gun. Carbine 80+ FPE.8- Sumatra cost less9 - Regulating is not a realistic optionIf I was buying a 25 for hunting it would be a Sumatra Carbine.
Rdsail, I believe the reference to small/medium was pertaining to the size of pests intending to be taken with the gun, not the rifle itself.wrt the bell curve vs downward slope issue, it really all depends on the application. In the case of a dedicated hunting gun being used to only take 3-5 shots at a time where maximum power is needed, a downward sloping shot string isn't generally that big a deal. But a gun to be used to take out as many pests as possible in one outing or to be used for target shooting would be better served with a nice long bell curve.
