I prefer Shieldon over Cranidos, whose evolution just looks like a post-puberty version of itself (talk about bland evolutions). However, Shieldon has been giving me a lot of headaches the past few years because it is still one of the mere five Pokémon I'm missing in my National Dex, because I have Diamond. No one else around me has Pearl or Platinum, and I fear this is gonna be the one Pokémon I will never find...
