It's actually not better tech, instead it's more complicated, more error prone and less durable ways to use the same technology that produces more space for a lower price. MLC is pretty much okay but TLC is a little too fragile and low performance in my opinion. I prefer spinning HDD's over QLC since the spinning drives have predictable performance.
Some QLC drives perform quite well. And of course for any workload that is primarily reads, they're totally fine. I use one to hold my Steam collection.
