I can actually get down to 32 with that box, but there is no need as I notice no difference using 64 samples.

This is the key factor for most of us, that getting down to that 'it makes no difference' low level is low enough.
The big issue then becomes one of scalability once the round trip latency is low enough not to interfere with any tracking you might want to undertake through the app.
Scalability in this instance meaning how complex a project you can run without having to increase the buffer size so that you don't end up having to switch between settings when you are performing different tasks.
It's one thing getting world beating low latency scores for competitions sake but it's far more convenient if you can find a spot that allows for trouble free through the app. monitoring AND glitch free arranging and mixing capabilities at a single setting.
As ever Danny cuts to the meat of the issue.
