That depends on the adversary. For something I don't want to get into the hands of local law enforcement (outside US), Wickr might be better than text messages. But I trust my network provider more when it comes to keeping the data safe, if I don't mind that local LEO agencies can readily access it. They are under strong legal and contractual obligations not to disclose the information to third parties and have better funding than Wickr. Wickr probably does a pretty good job, but they might be backdoored (ie. keep plaintext of communications and/or metadata) and might get hacked and leak the data and release it in the internet.
