The power reduction you see is sometimes called folding and is done to
protect the final transistors. An assessment of the antennas you have or
contemplate with their SWR curves, and whether you will be operating
barefoot or not should tell you whether tuning will be required.

Some will want to handle the tuning chores with a high power tuner that will
also do this for a transistor external amp.

For example a K3, KPA500 and KAT500 would not need the tuner in the K3.

If you expect to use your K3 at a field day, get the KAT3.

If you get it and never use it you can sell it in a heartbeat here on the
reflector.

Another of those very individual decisions.
