Based on that story? 2014 5e. No question. It sounds like your group is fatigued from trying alternatives and not finding one they can all agree on, and that fatigue has left them craving familiarity. Something they all know, and they can all be confident they’ll like, even if it wouldn’t be their first choice. You’re not going to get that from Level Up, or Tales of the Valiant, or even 2024 5e, because none of those are “everyone’s second favorite system.” They’re all built on the same foundation, sure, but they all take their own liberties with it, in hopes of standing out in their own ways, so that they might become
someone’s first-favorite system. And that’s just not what it sounds like your group needs right now. They need boring, familiar, safe, reliable old 2014 5e. For now, at least. Maybe once you’ve gotten back to a place of stability, you might consider venturing out to one of the newer 5e variants. But don’t try to jump right to that. Take it slow, stick to the stuff you know.
