I am just in the process of researching CNC myself but my understanding of the difference between 2.5D and 3D is that 2.5 can control any 2 axis at once and 3D can control 3 axis at once. I think that both the machine and the software that creates the tool paths both have to be able to handle that. Both can achieve a 3D relief carving so I am not sure under what circumstances or types of cuts a 3D machine would be better.

Your best bet may be to find one of the stores that can demo the machines you are interested in. Describe what you want to do and see if they can show you an example. My Rockler store has a demo every now and then and they have examples of their results on display.
