Are you debugging non-NXP targets?
Are there licensing requirements with your debugger that would prohibit using the debugger for production purposes, and are said requirements enforcable in your jurisdiction?
Do you need it to go any faster? Are there features offered by the other debuggers (HW breakpoints, etc) that you can use?
Does it work OK for you?
If no, no, no, no, and yes, then it's just fine for you.
