RAX120 WAN Aggregation vs. MultiGig Port

[cjmiller1994]

I recently bought an RAX120 and CM1100 Modem. 

Both are capable of WAN aggregation. The RAX120 also has a MultiGig Port.

My question - is the WAN aggregation typically better than using the MultiGig Port?

Or, are they not mutually exclusive?

Since the CM only supports 1Gb connection rated speeds. You might give LAG on the CM and RAX a try.
