Strike vs River BTC cost comparison

I did a buy preview of $500 using Strike and River to compare the cost for lump sum buys. I did this within 20 seconds of each other to accommodate for the potential volatility in price.

If I am reading this right, Strike has a lower spread AND transaction fee. I do like River’s UI but if Strike get me more bitcoin at a lower cost basis, I may start using it more.

Anyone else notice this or am I completely wrong here?
