Microsoft Edge

Edge inherited Chrome's engine and then differentiated on the chrome itself. Its standout is vertical tabs: a collapsible left rail that stacks tabs as a readable list with full titles, scrolling instead of shrinking, which fixes the horizontal-slivers problem that plagues its cousins. The trade is a crowded frame. Edge packs the toolbar and new-tab page with collections, sidebar apps, and shopping widgets, plus a sidebar that nudges constantly, so the interface that solves one clutter problem invents another. The omnibox behaves like Chrome's because it is Chrome's. Where Edge asserts itself is the surrounding furniture, sometimes usefully, often as a vector for Microsoft's own services pushed through banners and defaults you have to actively decline. Strong bones, noisy upholstery.
