These are two different things, which you're talking about here. Not old and new. If you're saying that you have Windows 10, then both of the menus there available, use what you want.
You're mistaken. Yes those images are two different examples of different styles of menus. If you need matching examples because you're still confused, feel free to ask.
Not only different styles, but they are fully different menus. And what You exactly want to do? To make faster open some of them? If yes, then they both will open very quickly when the op system OK and clean.
