At the same price, I'm sure that everyone would prefer DDR5 for any new purchases.It has many advantages beyond the speed, or in your case, the obsession with it being a "one up".
All I'm pointing out is that every previous memory transition has been beset with issues.
Usually the next gen has been expensive and short of supply so the manufacturers see it as a chance to push prices back up as usually the old gen has been around a while and has excess capacity etc.
The first few iterations of next gen have also often been no faster than the old gen's still cheaper higher end parts.
Eventually, a few years into the next gen, most of these problems will be gone.
The cautious buyers like me can then thank the paid-through-the-nose early adopters.
So I'll thank you in advance while I sit and watch.
