The main differences you have to take into account are that the Edison has a more powerful CPU and it runs on a slightly newer kernel. So, it is compatible with newer drivers, packages, etc.
Even if it's a hardware difference, it is important to point out that Edison includes the module + Wi-Fi + Bluetooth in one tiny package, this makes it very convenient as you wouldn't need additional hardware in order to connect to the internet or Bluetooth devices. The Edison also makes it easy for users to develop custom boards that can be adapted to specifically their needs. It also runs on a much cooler temperature than Galileo.
Nevertheless, this would only matter depending on your project's needs. And if your Galileo has been powerful enough to run it, you might find a slightly quicker version on Edison, however, the differences might not be noticeable.
Thank for replying, Peter, from your reply and the threads/comparisons above my own answer to the question
Intel Edison Kit for Arduino > Intel Galileo Gen2?
is undoubtedly a plain "yes". Furthermore, my own answer to the question
Are there several tasks/IoT implementations done in Intel Galileo Gen2 which would be too difficult to be made in an Intel Edison Kit for Arduino?
is undoubtedly a plain "no".
I do not understand why Intel would still offer both, but I guess it is a strategic decision, I'd not ask about that.
Edit: maybe it's a matter of price, Intel® Maker Platforms: $69.99 vs. $44.99
