I find tree style tabs very effective in things like oncall/learning/investigation situations because they act as kind of breadcrumbs/grouping solution. Like list of issues -> issue -> [log search, similar issues search, metrics etc]. You get stuck/wait for something then go to next issue, but have chance to return back to your entire context. And when you finished you just close entire subtree and move on. With linear list of tabs (or even groups in chrome) it is much less convenient.
