Purely latency wide Fix is slower than a very high performance C++ Api. That is why most hft houses use the direct C++ APIs offered by exchanges and don't use FIX. But Fix is still easier (not trivial) to implement than having to target the entirely unique non fix api each broker offers.

If you do not do colocation, FIX should be the best choice, actually Nasdaq's OUCH and NYSE's CCG both are simplified binary version of FIX.
