MP40 or 10's

I would also do the same two mp 40's

I have 2 MP40's on my little old 77 gallon, so my opinion would be 2 more MP40s for your 120 is almost a no brainer. For a while I considered getting an MP10 for the back glass since my 77 is a narrow tank, but the flexibility of the EcoTech drivers allows me to run the 40 on the back glass limited to a lower speed while still acting as a slave of the master, so it follows the selected mode, which in my case is Tidal Swell.

With my 180, I do 2 returns in the back corners facing inward, 2 mp40's with alternating reef crest in the back middle facing forward, and a wp40 wave from right to left.

Zero dead spots.

Edit: Should read that I have 3 MP40s, not 2.....
