Can anyone tell me what the best practice is for the ACE 4710 appliance. Should I deploy it in routed mode or source NAT mode. And what can be the pros and cons of each method....

The advantage of running SNAT is the ACE is deployed in a "one-arm" mode. In this deployment the advantage is the ACE does not have to process all traffic as oppossed to being directly in the transit path when deployed inline (routed).

In one arm mode you can use either PBR or SNAT for server return traffic. One arm mode also allows for direct server return butlimited to L4 load balance.

In routed mode the ACE acts as the server default gateway.

Routed mode is the easier of the two to configure.

but what if you want to see the origin of clients using the load balancer.

I would have to check to see if the GUI shows the translations.

If you want to see the clients then go with routed.

Either is method is commonly deployed.
