I main Paladin. Some people say it's boring, but I don't find it to be so. It's the safer of the two tanks because you have a lot of defensive cooldowns and all of them are off the GCD, which makes me a lot more comfortable going into fights I don't know. There's just something wonderfully fun about being all but indestructible. The big down side of either tank class is your low damage if you go with a standard vit build. It feels like you're beating mobs with a wet noodle. I've gone over to a very aggressive build (crit/det instead of parry, pentamelded accessories). In the end, it's really made my character a lot more enjoyable.
