Is wonderboard or backer board better than plywood

hello, I am about to tile my floor and have heard that backer board/wonderboard was better than plywood. I worry about smells/ off gas or chemical problems with it because I just had a damaged prefinished floor that smelled like poly and was cupped so we had to rip it out. Any tips would be great. Thanks!
