Vanguard Target Retirement 2040 Fund vs VTSAX

Hi,
I have a RothIRA it currently only has Vanguard Target Retirement 2040 Fund in it. I’m thinking about selling all stocks for Vanguard Target Retirement 2040 Fund and buying VtSAX. So, I would only have VtSAX in the rothIRA.

I’m thinking vtsax perform better long term.

What are your thoughts?

Thanks in advance!
