Basically, FIX message is transferred in text format, while OUCH transfers messages in binary format, which leads to OUCH could transfer message in slim size and occupy less bandwidth over the network; for achieving higher performance over transmission.
Everything has a trade-off. Below has listed some comparing items between both for a reference.
Data Format
FIX: Text
OUCH: Binary
Data Size
FIX: Big
OUCH: Slim
Data Length
FIX: Variable
OUCH: Fixed
Data Sequence
FIX: Explicit
OUCH: Implicit
Universality
FIX: Industrial standard; generally supported & accepted by most exchanges and clients
OUCH: Proprietary; limited to specific exchanges

The main difference is that OUCH is a protocol that is specific to the NASDAQ stock exchanges. The FIX protocol is a standard that is supported by most exchanges.
The OUCH protocol is a faster protocol as it is designed as a low level native (binary) protocol, but as it is specific to NASDAQ exchanges you will have to have another module based on FIX to connect and trade on other exchanges.
