I upgraded from the regular style, chrome-plated faucets to the SS Perlicks.
I had a HUGE problem with mold growing on the inside of my regular faucets. Within a few days time, if I did not spray out the faucet after pouring, I would have mold spots in the spout and clumps of mold around the "piston" of the faucet. Even with spraying out the faucet, I would still get the mold, but it would take about 2 weeks to grow. I always had sticky faucet syndrome with those old faucets as well.
The Perlicks have not grown ANY mold, and I do not clean them. I let them drip normally into the drip tray, and they stay clean on the inside. I occasionally shine a flashlight into the sprout, and every time it's still as clean as new. The way the Perlicks are designed, I've never had a sticky faucet with them.
The upgrade, for me, between the regular faucets and the Perlicks was great move.
I'm not sure how different the chrome plated ones hold up compared to the stainless ones. I'm not saying that this happens to Perlicks, but I have heard of the regular chrome plated faucets having the chrome plating peel off over time, so this may be true with Perlicks as well. I decided to avoid any possible problems, and spent the extra money on the stainless ones that I was sure to have no issues.
