You don't need to do both anyhow, compression test is just as good as a leak down, just the reverse. Compression the piston builds the pressure, ;leak down you pump the pressure into the cylinder. Only thing a leak down might spot that may not show as good on a compression test is minor scoring, major scoring will show on either. On a 4 stroke the leak down will also spot bad valves or valve stems, gaskets.

If the cylinders build good and even compression there can't be much wrong with the rings or the walls. I really doubt you will have any issues but it is worth doing if you have a compression tester, it only takes a few minutes and it will easy your mind.
