Clean install is the best for any OS in my experience.
Few months before i upgraded to win 10,I got many issues such as Start not working,Cortana,Boot problems etc... So one day i became too tired of it and i backup my all files to one drive. And i made a clean install of windows 10.Now my computer is fast than before.
