That Crucial drive is also QLC, same as the Intel. Anandtech has a good review:

I literally found out about it the day after my Intel arrived; for an extra $10 I'd have gotten it instead due to the extra ram, but oh well.
TLC and QLC refer to the way the cells are used - QLC requires more voltage to write a value, which damages the cell over time. This causes lower durability and slower writes as compared to TLC, but allows for higher density.
If you're concerned about durability, I'd go with a TLC drive. Depending on who you believe, the HP EX950 is rated for either 650TBW (Anandtech) or 1400TBW (Amazon), and 0.36 DWPD (Drive Writes Per Day) compared to the Crucial's 200TBW and 0.1 DWPD.

One note: M.2 refers to the physical form factor of the drive, NOT the connection type. That will be either NVME or SATA. The latter has slower throughput, although practically speaking, not significantly so.
If I were you I'd probably format the existing 2TB drive after getting your SSD up and running and use it for storage on the machine. Another option, as someone pointed out, would be to get an external case for it, which would also allow you to use it as a target when cloning your SSD for backup.
