Depends on what you are doing.
An analogy might be like asking "What gear should I drive in?"
Low latency is needed for anything to do with live sound. If you are monitoring your input live through the mixing board, you need < 11ms total round trip latency. If you are just mixing already recorded tracks, set it high (eg. 1024 samples) to save CPU for processing.
For live use, set it as low as possible to still have stable operation with the plugins you want to use. 128 samples is a good starting point. If you have a cheaper USB interface though it might take a setting of 64 samples just to make < 11ms which will leave you without much CPU headroom left for a lot of plugins.
You should get a baseline on your system to see what you have to work with. Run a loopback test with each of your interfaces separately and with them in an aggregate device together to see what you have. If you can hit < 11ms at a 128 sample block size you'll be golden for dialing up lots of plugins at that latency.
