Huh?
I don't see 1/2 over 3/8 or vice versa as being an issue. I suggest that ya'll get your battles straight!
This is bound to degenerate into a useless "US vs German" thread, just like we had (and we had two!).
Bottom line, there's merit in both, and unless the flow rate is unusually high, the difference will be minimal.
I'll post pressure drop figures from Hazen-Williams, for 3/8 and 1/2" ID, for various flow rates, and various lengths of tubing, if anyone's interested, to support pHaestus' Darcy numbers.
