As an embedded developer, I would agree that there is this sentiment that arduino is somehow inferior, bigger code sizes, worse code quality, training wheels, etc. However, I've recently used a couple different Teensy boards in some personal projects, which are a line of 3 or 4 different freescale kinetis cortex M0-M4 parts that have their own plugin for the arduino IDE. I've been very impressed with the breadth of libraries, and how well it all works and integrates between different boards. The code is well written, and looks like it could easily be dropped into arm-gcc. Maybe Teensy is the exception, but there are some high quality Arduino codebases out there. Not being able to use in circuit debug tools is a huge pain, however.
