I like Bar Sto barrels and from what I have heard the other barrels mentioned are quite good too but the only reason I have them is to change to a different caliber - i.e. 40S&W to 9mm.
I've shot 100's of reloads in my G23 with no issues. I use nickel plated cartridges with Montana Gold 165 gr FMJ and usually run 90% of max powder Accurate#2 .
There is some concern about shooting straight lead in the hexagonal Glock barrels and a lot of folks will switch barrels for that reason but I reload with FMJ's so no need to switch.
