Most of the browsers today are supporting CSS Flexbox. The problem with it is the complex syntax. On the other hand, CSS Grid looks more refined and well structured. It's still not supported by many browsers.

I don't think this is a good question, because I already use flexbox (so I cannot look forward to it) and flexbox and grid have different use cases, so they are not really comparable...
As such, I had to tick CSS Grid, since it's the only thing I look forward to (have a broader browser support)!
