Best kind of wigs?

Shout out to all the beautiful wig wearing women out there in the audience!!! Lol anyways, I'm hear to ask you ladies a question. In your opinion what is the best type of wig to buy? I'm doing some shopping because I'm planning on shaving my head sometime in the near future and I want to have at least one wig as a back up for those days when I don't necessarily like my bald head. I already have like fifteen billion hats (it's like an obsession, they make me feel safe, I used to wear them every day even in the summer and at school when I could get away with it) so I'm all set on that plain lol. I just wanna know y'alls opinion on whether to go with synthetic or real hair. Also what is the best place to buy a wig without spending a butt ton of money on it?
