Best kind of birthday cake?

Its both mine and my boyfriends birthday on sunday and were having a bunch of people over for a bbq birthday party and i am thinking making my own cake would be cheaper, I am just trying to figure out what to make. I have this recipe for a devils food cake and buttercream frosting. it looks good but i just don't know what to make since some people might not like chocolate how do i decide why type of cake to make or does it even matter
