One of the things I liked about Beat Scape that Matrix doesn't do is that depending on where you clicked on the pad the volume of the sample would change. I don't think that it is currently possible to control volume in Matrix View based on where you click to activate the sample, since the volume for the sample is controlled by the track itself.
I like Beat Scape. I like Matrix View. I only use either when I'm really really bored though. :-) I have too much live recorded music to mix to mess around much with Beat Scape.
I once did sample in some sounds from a favorite song some of my friends play and I made a remix of it triggering loops of their song's various tracks using Matrix View.
I do install Beat Scape with X2.
