Either way, they're all pretty terrible if you think about them for a while.

Though I probably like destroy the most, it gives you the arbitrarily "All synthetics will dies because space magic" thing which kind of ruins it for anyone that really liked EDI or the Geth.

Control seems fine at a first glance but then you realize you're essentially doing what the Illusive Man has been advocating and you've been challenging for the entire game. If Shepard effectively changes/replaces the Catalyst, how long would it take for it to become another Catalyst 2.0 deal? Shepard has a strong will, but he/she is only human. Will their personality REALLY keep the Catalyst in check forever? What's stopping Shepringer from finding their own "solution" to a problem?

Synthesis also bothers me quite a bit. For one, you're making a fundamental change to the galaxy without anyone's consent but your own. You're basically going against the "Progress through variety, overcome through diversity" theme by turning everyone into a techno/organic hybrid. That, and we have no idea what the lasting effects of this option will be. What pisses me off the most is how little sense the entire option makes. Look, I get that the line between magic and technology gets pretty blurred as we progress but this just throws what little "suspension of disbelief" I had left out the f***ing window. I can only take so much space magic before it starts to get silly.
