There are things to consider. I would not hesitate to recommend the MC. Its the CS standard. it works with all DAWs and some non DAW programs. Mine is the first version and has not let me down in all these years.
If you want cross DAW usage its the one to get. On the other hand the VS700 is meant for Sonar and has the tightest integration of any CS for Sonar.
I don't like the audio and CS being in the same box but that is just me.
The VS700 can be used with other DAWs but as a MC.
I think one has to look at what each offers and go with the one that meets ones needs best.
There are many to choose from and some that could be gotten from the used market. Some are no longer being produced but they still work.
I would look around and pick what is the one I find the best for my own needs. No one can say this particular one is the only one worth getting. No matter which on it is.
You have a choice.
