Default output transformer impedance choices

My new amp project is down to selecting OPT trannies and I am torn between 3.4K and 4.5K options for my KT88PP circuit. I know that the 4.5K will have a little lower distortion and that the 3.4K will provide more output power. What else is there to consider between my choices for a KT88 PP amp?

TIA

Operating point, and how the KT88s are connected.

Id probably go 4.5K. As you go more toward triode, and higher in voltage, larger loads are more desirable.
