Feature Before and After share point Visual Upgrade from 2010 to 2013

Hi All,

Recently, we have migrated the SharePoint 2010 server  to SharePoint 2013 server but we dont want to go with Visual upgrade and continue with old visual experience(SP 2010). 

So my question\Query is.. 

1. Which feature will be and will not be available while using SharePoint 2013 server with old visual(SP 2010) experience?

2. Which feature will be and will not be available while using SharePoint 2013 server with visual(SP 2013) upgraded experience?

Can anyone provide me the link? 



Thanks and Regards,

PR
