Also worth noting how different the different goals/approaches differ between the WebKit and Blink teams. The WebKit team is very deliberate in their development, only committing to new features once they have some level of assurance that it can be done with minimal negative impact to efficiency, privacy, and user control where the Blink team moves almost entirely in interest of getting as many new features out as quickly as possible with comparatively little regard to negative side effects.

Both approaches are needed to maintain a balance and to preserve real choice for users — there is no practical difference between Chrome, MS Edge, and Brave because their differences are skin-deep at best.
