5e is much more forgiving. However, when you're starting a campaign with 1st level characters, those are usually pretty squishy (compared to higher level 5e play). I've had numerous 5e TPKs, most of them at 1st-3rd level.At first, the PF2 makes sense as its a game where the numbers easily stack against the players and if they dont use tactics its wipe city. Though, im a little surprised to hear 5E has a similar problem. I find 5E way more forgiving both in numbers and tactics.
