eGPU Macbook Akitio thunder 2 vs Node

[Cristal1234]

So I am currently trying to build an eGPU for my 2015 mBP 13".
My question is: should I buy an akitio thunder 2 and go with the classic build or buy an akitio node/ thunder 3 and an adapter tb3->tb2?
And are any performances differences between these(according to my mac)?
Akitio Thunder 3/Node with adapter tb3/tb2 will work faster than akitio thunder 2?

I can't comment on the Thunder 2, but I've been using the Node with the Apple TB2->TB3 adapter connected to my TB2 Macs and Windows laptops, works great and being a TB3 enclosure means I'll get a bit more out of it if/when I upgrade to a laptop that has TB3.
