One another +1. For me it's a question of embedding. With SparkConf/SparkContext I can easily create larger projects with Spark as a separate service (just like MySQL and JDBC, for example). With spark-submit I'm bound to Spark as a main framework that defines how my application should look like. In my humble opinion, using Spark as embeddable library rather than main framework and runtime is much easier.
