If money really isn't the issue, then get both. The remote is great and makes for a quick small and powerful package. However, the RJM is an absolute monster and the choice if you want a lot of control. The editing (computer or on unit) of the MMGT is quite easy and ultimately you can flash it for different rigs with a USB stick if needed. I've actually got the MMGT controlling several rigs for studio work at the same time.
I can grab either setup depending on the need.
If you can only get one then follow this:
- You are a control freak or just need it = RJM
- You don't need control of everything or just don't want to mess with it = REMOTE
I like the remote, but I keep running into little things that you cannot do with it that I can easily do with the RJM. I do however, love the ease of use around core functionality of the REMOTE. In the end I use both for different situations.
