Verdict
The clearest difference is price: Alien Defense at Free against DefCom TD's $1.99. Alien Defense also leads on update cadence (every 3 weeks vs every 41 months). DefCom TD's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
