Almost any native UI framework (iOS, Android, WPF on windows, etc) has better layout options. Some of them like iOS have options that are not as beginner friendly (AutoLayout), but they are still better overall if you are trying to develop an application instead of formatting a document. Many other UI frameworks have had Flexbox type layouts, a technology W3C has only just recently realized is a good idea for 8+ years (probably much longer).
