OT: Finals time - NBA or NHL - which do you follow and prefer?

It's that time of year when two of the four major professional US sports are in their Championship Final series.   Those two sports are - the NBA and the NHL.

Do you follow both?   Do you have a preference for one sport over the other?   If so why?

And, if could only watch one of the two sports final series - which would you pick - the NBA or NHL?

If I had to pick one, I'd pick the NHL, hoping the series "goes 7".
