The complete CMJ article : 

It's a bit like MIDI, where a lot is defined; despite being a domain 
specific protocol, MIDI is often used for non-musical use cases with 
note on/off or pitch bend messages... So when possible, using OSC can 
make a lot more sense.

It's true that OSC does not have Zeroconf capabilities (like the popular 
NDI protocol for sharing video streams between applications); OSCQuery 
tries to fix that (and other issues): 

As for OSC timestamps, it's possible to add them in the OSC messages, as 
an application specific feature, but it would add more latency. To avoid 
jitter, one possible hack would be to use lossy audio streams to 
transport control data (but it could be a bad idea).
