The 6.05 will be very slightly more accurate, the 6.01 will increase power a bit. The first factory (Laylax/Prometheus) barrel will give you similar performance to the PDI, both brands make excellent barrels. The KM barrel is decent enough, but it is a brass barrel, so it is not as durable as the PDI and Laylax barrels. But then again, we are talking about a pistol here, so it is not going to see gazillions of rounds, so if the KM is significantly cheaper it might be a good deal.

Also, I usually recommend not to upgrade barrels on TM pistols as you get very little performance increase for the large amount of money you are spending, but the MK23 has a crappy aluminium barrel that is not very durable, so it is worth it. Note that the best performance upgrade for any pistol remains a good hop up rubber, and as such, if you upgrade only the barrel, you are not going to see a major improvement in accuracy or range, you really need a better hop up rubber too. The PDI W hops and the Firefly soft rubbers are great performers, although there are plenty of other great rubbers out there.
