Which is better for heavy office work and many browser tabs?

The MSI PRO 12M. Its Core i7-13700 has 16 cores and 24 threads against the HP's 6 cores and 12 threads, so it holds up better under sustained multitasking.

Is the HP worth $200 more than the MSI?

Only if you value the 100 Hz screen, DDR5 memory, and USB-C. The HP is refurbished and has fewer CPU cores, so the MSI is the better value on paper.

Which has the better display?

The HP. It lists 100 Hz, 350 nits, 100% sRGB, and Low Blue Light. The MSI lists a matte FHD IPS panel with no refresh rate or brightness figures.

The MSI starts new with a full manufacturer warranty, while the HP is refurbished with a shorter typical coverage. The MSI's 16-core CPU also ages better for demanding work.

Can I mount either on a monitor arm?

The MSI lists a 75x75 mm VESA mount. The HP listing does not state a VESA pattern, so check before buying an arm.

Do either have USB-C?

The HP has two USB-C ports at 10 Gbps. The MSI's listed ports do not include USB-C.
