Objectively, the syntax for both are horrible (based on BASIC I believe, but still). Magic numbers, hex numbers, huge number of function parameters, obfuscated parameter/variable names, etc. It all leads to barely readable spaghetti code even in the most well-written UDF examples. And... good luck trying to get anything but the blessed-but-insufficient-for-serious-work IDE to work for you.

Help files are decent... but if you need help with a concept/idea/implementation - you are much better served to seek that help anywhere except from AutoIt or their forums. Which is sad.
