There is no comparison between getting バラ and daisies... バラ are the most gorgeous and aromatic, not to mention being the 花 associated w/ LOVE, so romantic... they carry prestige too.
Daisies are so much もっと見る cheerful, but バラ smell better, so whatever the person likes more. I would prefer daisies because they are joyful and もっと見る unique than roses.
