Kind of hard to test them from the internet. What do you mean by good.

Without X-ray vision, I'll guess the OP has 3 different brands of 2N5401 and wants to know if theyre genuine.

OK, have at it!

OK, educated guess:

Left is Korea
Center is Japanese
Right is possibly a cheap knockoff

In the middle is the best one. The "Y" I think represents a higher class of hfe, and they do have high hfe, just measure it with DMM. Whatever the brand, if it measures better then I think it should be a better transistor.
