As Crusader was my first Stronghold ever, I believe it's also the best of introductions to the series. Aside from that, I think the skirmishes are the series' strongest point. Yeah, they might seem a bit harsh to the newbie, but they're not THAT harsh.
I believe that even the absolute beginner can take on Sultan Abdul (1st Crusader Trail), even if he has to try it again a couple of times. The game mechanics are simple enough for this to happen.
Then again, this is how I did it. Judging the matter from a distance, the original does indeed introduce you in a smoother and friendlier way to the game. Myself, I like to play the original just for the nostalgia factor and the music. Crusader is the way to go imo, it has that absurdly fast and dynamic gameplay in skirmish mode, something that the original does lack.
