SwiftKey's features are somewhat more helpful than Gboard, a veteran in the world of keyboard systems. While some features are on par (swiping pace or word abbreviations), there are some places where both keyboards give each other a tough competition.
When you really need quick predictions of lightning and an integrated clipboard manager then SwiftKey is probably your keyboard. Otherwise, GBoard is appropriate for you if you're searching for a fun feature with the added benefit of Google Search.
