Single leg leg press vs both legs?

Hey guys! So I'm just wondering what the difference between the two? I wanna grow some nice glutes, and I thought that using both legs higher up on the platform would target my glutes more, but now I'm hearing using a single leg might be better. What's the difference between the two, and would I be able to still grow my glutes effectively with using both my legs on a leg press?

Also a side note, I'm thinking of having my split being PPL, rest, and repeat. Is that an okay split or should I reconsider?
