I believe polished chrome is the most durable and easiest to clean finish. The PB and BN finishes today are usually PVD, and I do believe that is very durable as well. You will pay up for any finish other than chrome, just like you pay up on appliances for anything but white.
Brands you will get a million opinions. I and a lot of others will suggest that a very widely used brand like Am. Std, Delta, PricePfister, Moen will be easiest to service and get parts. Very few people will ever say anything bad about Delta. I personally have also had good experiences with Am. Std and don't like PP so well. Others will have the reverse opinion. Find a faucet you like. You have to look at it! And if you go with an exotic brand realize there could be hassles down the road. I always recommend to buy 2 and keep one for spares. Not everyone agrees with this tact. Just offering my opinions.
