Not only that

• springer holds a share of qwant and springer is a rubbish company.
• qwant on mobile shows you the mobile sites of the search results instead of the “real” website. I think that’s a tiny but important difference.
• qwant doesn’t show you the protocol, i.e. http, ftp, etc. And hides SSL encryption of sites on mobile.
• qwant hides the subfolder structure of the site you are about to enter on mobile.
• qwant forces you to choose a country and only serves higher income countries. Qwant shows you different results in different countries. It’s not just an english or french web, it’s a canadian french, frensh frensh, etc. Web.
