Spectres, definitely. While a single unupgraded Temple is better than a single Spectre, all you need is 2-3 Spectres to take down a ZOMG. They're also more cost effiecient, Spectres are only 20,000 a pop while the temples are 100,000. (Thats not to say Temples aren't good, just that Spectres are more cost efficient. Multiple Spectres are better against one ZOMG, one Temple with good sacrifices is better against multiple ZOMGs.)
