Even Samsung "Pro" flagship consumer SSDs are using TLCs nowadays. I want to believe they found a way to make TLCs suck less. At least, they can sustain the throughput on benchmarks, but I'm yet to find some benchmark on durability (vs past MLC iterations).
Samsung rates the 990 Pro 1TB model at 600 TBW vs 800 TBW from the 960 Pro (MLC)... It's bad, but a shot I would take for the much better performance (4 times IOPS) if those numbers are to be trusted.
