Honestly, the big thing that the Pi has is the support and mindshare. Compared to many equivalents (e.g., the Banana Pi) you'll find much better documentation and have a much more polished experience with a Raspberry Pi.
The only question, for me anyway, is how much value I put on that experience and whether the increased cost is worth it.
