I'll jump in though I'm not familiar with the V3. I've had an MXT Pro since October 2010. I also own a T2SE, a Garrett AT Pro and a Fisher 1266X. All are great machines and I'm still learning the T2. The MXT is still my primary machine. It is a real work horse - tough as nails and though a newbie can start out with it, there's plenty of growing room. My favorite coil is the White's 10" DD. I dug a Confederate Block A Coat Button with the MXT this week. If you get the MXT, get Jeff Foster's book and you can learn some more tricks for getting some more depth out of the MXT.
