Better to give it space to grow into rather than restrict it with 120. Windows 10 is unlikely to ever need 250 gb (talk about bloat) but you may want to install a game or two on it and 120 soon feels crowded with a few games on it. You don't want to fill an SSD up as then you lose the benefit of its speed.

Win 10 can be 15gb if you don't have a hibernate file and restrict page file but that is just also restricting yourself in the long run.
