Let's not start that again. 4e models a very different reality than the one 1e does, not the least of which is Gygax never suggested that hit points ought to be easily recoverable from a night's rest. Let's not pretend otherwise. You can fully describe the reality that 4e models and defend it without resulting to spurious claims that it isn't any different than the one modelled by 1e. There are two huge differences.
And while it is true that every edition is horrible at modeling injuries and generally does not try, injuries in 4e are actively deprecated as even a thing. There is a scale to this. There are differences in degree. The last thing we need is to resurrect one of the great battles of the edition war, namely, that 4e was actually truer to 1e than 3e had been.
Go to a grog board and find out their opinion on 4E lol. Go there and compare it with 1E, if you think they don't like 3E their opinion of 4E is even lower.
Rather than argue about what models damage better I think its just better to look at rapid healing vs 1-3 hp. What one you like better is up to you. OSR has combat as dangerous, modern D&D is more kick in the door. Kick in the door in AD&D you might find yourself a level or 2 lower (or dead). Ones gritty ones not, what you like is up to you.
It was quite funny running AD&D for modern gamers, I did warn them about the differences going in. Sure enough they were tapping the ground with a 10' pole, rolling marbles around looking for slopes and using Elves to look for secret doors. Well actually everyone did once they found out everyone was roughly as good at it as anyone else.
