The benefits of buying an m2 is that you have a higher chance of destroying your enemy, though buying an m(?) can be very costly. My Twins has 19 micro upgrades and it acts very much like an M1. The choice is yours, but I would suggest Micro upgrading it unless your in a hurry.

Hello! I was just wondering if anyone could help me. Should I buy M1 Twins or Thunder? (Rocket is also an option) I mainly use Viking M1 and Hornet M0. Or should I buy a Hunter M1 or Hornet M1 first?
