Hyphenated last name, help!

So I was planning on giving my daughter my last name but my boyfriend is extremely upset about it. He assumed she'd have his last name and is trying to convince me to at least hyphenate it so she can have both our last names. I'm not crazy about the idea because our last names sound wierd together. I've also heard things like it's a hassle and not worth it to hyphenate it.

Looking for any opinions, experiences or insight on hyphenated last names. Thanks in advance!
