OK, why do you want to strip them? If it's because you want to paint them, take them to a powder coater and have them sandblasted and powdered in primer, then sand and paint to your color. .
I have the equipment to do powder myself, but sandblasting does not always work out so good. It takes 2 to 3 coats or more to get good results. Bare metal works much better than pitted chrome.
Good chrome you can just scuff and coat. So to answer your question it is alot more work to deal with nasty chrome. If I could get a plater to drop it into an immersion tank the chrome and nasty plating diisapears leaving me with bare metal.
As a rule of thumb parts with alot of surface are like fenders need to be near perfect to get good results.
Things like kick, brake and shift levers usually come out great no matter what.
