I have a Prosport and a TX200HC both in .22 calibre, both are unmodified guns. Out of the two I find the TX easier to cock and load the pellet. The underlever on the Prosport is a little easier to close up due to not having the anti bear trap button. Which shoots the best, it comes down to personal preference. In my opinion the Prosport shoots marginally better but ask someone else and they may prefer the TX. Out of the box I've found the only springer I own to come anywhere close is the Walther LGV Master Pro, this includes HW35, HW77, HW80, HW95, HW97 and HW99
