Get what you personally want. Most people get normals first because of many reasons. They may not know there are hundreds of common color and pattern morphs available, they do not wish to spend the money on a first snake 'just in case', they prefer the look of normals, they are cheaper, etc etc.

I personally got a Pastel as my first BP because I knew I wanted to breed this season and a male Pastel is gold in my plans.
