KDE Upgrade - which one?

[Dana J. Laude]

Greetings,

After a brief stint trying SLED 10, I'm back with Kubuntu.  I previously 
had dapper with 3.5.3 installed but I notice that 3.5.4 out.

Since this is basically a stock fresh install of dapper with 3.5.2, 
which route would be more suitable, 3.5.3 or 3.5.4?

Thanks,

Dana
