I think it's far more important to get a saddle that actually fits you correctly then think about how much/little padding you want/need.
Any good LBS will be able to help you sizing you up i would think.
I was in agony for a fair few trips of 20-30 miles then took my own advice & found my saddle was the wrong size, changed it to the next size up & the very next ride i did was 52 miles & i did'nt even think about my butt....which has gotta be a good thing !
Of course, decent shorts do help massively aswell i.m.o.
Good luck anyway.
I think you also need to consider your position.
I have never managed to be really comfortable on my mountain bike, despite the suspension, but on my road bike don't get sore. I think this is mainly due to weight distribution on road bikes.
