1. The UTC has a great variety of different items (Augmentations, Parts and Components), while the Series 11 only make use of Parts.
2. UTC infantry regenerates, Series 11 infantry also but Series 11 infantry are also repairable and Series 11 repair twice as fast.
3. While the UTC can't repair as fast as the Series 11, most of their units are tougher. Series 11 units depend more on stealth.
4. Series 11 units focus more on ground warfare than the UTC do.
5. Series 11 train their units in one building and make their items in one building (the UTC mixes these two things in several buildings).
