どっちもどっち, 大差ない

used to say that two things are equally good or bad, or that it does not matter which one of two things is chosen

:
Whether we leave now or later, it's six of one and half a dozen of the other; we'll still hit traffic.
今出発しても後で出発しても、どっちもどっちだ。結局渋滞に巻き込まれるだろう。
You can choose the red one or the blue one, it's six of one and half a dozen of the other.
赤を選んでも青を選んでも、どっちもどっちだ。
