Invest $10K in RDDT or RKLB

So I have $10K that I would like to invest into one of these stocks.

I use Reddit every day so investing in RDDT seems like a no brainer. But I have faith that RKLB is going to be very successful and it's low share price seems like an opportunity I shouldn't turn down.

If you had $10K would you put it all in RDDT, RKLB or split it between both?
