Apple recommends that you optimise AVCHD to ProRes 422 for both quality of results and speed of processing.
If you are not doing anything too complex you can get away with AVCHD but the only way to find out what is best for your modus operandi is to test both methods using near identical projects.

Do you mean optimize on import within FCPX or some 3rd party software before I ingest to FCPX?

I don't know whether it matters.
If you are importing directly from your camera/card it would make sense to let FCP X do it.

Keep in mind that you can always optimize even after you imported your media. Just select your media, ctrl-click and select Transcode... at any time.
Also, if you need more speed, you can edit using proxy media, which is supposedly much faster. Just remember to switch to optimized or original before the final export.
