In reply to ralphio:
In line with the earlier posters, I prefer mastercams (and have a couple of both). The mastercams are more reassuring somehow and are very well made. I like the fact they are a little stiffer but are still flexible. They were also very cheap when I got them, relatively speaking.
The warning about them rusting if exposed to saltwater is, apparently, true although I have not had any problems in normal climbing and haven't taken them to any seacliffs.
