In my experience doing a rechrome has been better. The original bumpers seem thicker and the chrome shop I use is phenomenal and cheaper than an after market.
They straighten and repair anything that needs to be done, remove all dings and dents, even rechrome the bolts. They strip everything first and then use the triple dip process after polishing. For my Demon they charged $275 each for the front and back. That is their flat rate and my bumpers were not in good shape. The cheapest I have found aftermarket is around $300 apiece once shipped. Just some info from my own experience.
