Choosing a protector

Hi All,

I'm in the process of selecting a encryptor/protector to protect my company's software, and trying to figure out which is the best (professional versions of each, with all features turned on).

So far on the list to check out and compare are:
Armadillo - strippers,unpackers are around. trial count resetter exists. like the fact that digital river owns the company, since they're pretty solid.
ASProtect - strippers,unpackers are around. trial count resetter exists. like the fact that some of their anti-debug features have stumped me at times
Licenturion - relatively unknown, at least IMO. haven't seen much, if anything, about it on the unpacker forums i frequent.

Could someone who's an ace at unpacking all sorts of proggies suggest the best way to make this decision?

Thanks,
Steve
