The only advantage in terms of gaming is DX12 support (if your GPU is compatible). There's also security updates as well, 7 will soon be unsupported (mainstream support has already ended and is on extended support until 2020).
And if you're doing a clean install, I found 10 a lot easier and faster to set up. The latest 10 ISO contains the recent Threshold 2 update so there's not that many updates to install after, for 7 even with the SP1 ISO there's hundreds of updates afterwards. 10 is also very, very good at automatically finding drivers too which saves a fair bit of time.
