better is a loaded word. they both will work, but where are sources, in the same room or elsewhere? do you need rf capabilities? you want internet browser?

HTM mx3000 RF is more stable- ie it works all the time and doesnt rely on wifi connection. HTM RF is also addressable so you can control 2 of the same model dvd players from one remote and have them not interfere with each other.

Netx is not ir addressable, but ipronto has internet and has larger screen which is crucial for multiroom app's.

if the ipronto had more stable rf like HTM then it would be a definate for ipronto by far.
