Definitely! The "Nightmare" is much better than overhyped Corpse Bride! Corpse Bride is not bad in terms of animation. But in term of story, soundtrack and fun it's far behind the Nightmare. I would say it's just another commercial "sequel"

As for Svankmajer, I can recommend you "
Faust". Also "
Otesanek" (Greedy Guts/Little Otik) is great stop-motion! Oh yes and "
Spiklenci slasti" (Conspirators of Pleasure) is great movie too! These were from the latest Svankmajer's works. But his older works are great too! Search for "
Moznosti dialogu" (Dimensions of Dialogue) or "
Zvahlav aneb Saticky Slameného Huberta" (Jabberwocky). It's hard to select the best one

BTW, stop-motion movies have a great tradion in Czech Republic (Svankmajer's and my homeland). If you like stop-motion style movies, check also Jiri Barta's films! For example his great "
Zaniklý Svet Rukavic" (The Vanished World of Gloves) or "
Krysar" (The Pied Piper). And we have not to forget about probably the greatest Czech stop-motion artist Jiri Trnka (also known as "Walt Disney Of The East")!
There are plenty of old Czech stop motion and puppet motion movies at youtube and some are also here:
