Which is better for a PS5?

The T500 with heatsink. The PS5 uses a Gen4 interface, so the T705's Gen5 speed is wasted, and Sony requires a heatsink on the installed drive.

Is the T705 worth it over the T500?

Only on a PCIe 5.0 desktop slot. There it is faster and, at $620.00 at Newegg versus $674.99 at Adorama, cheaper. On Gen4 hardware the two perform nearly the same.

Will the T705 work in a laptop?

It fits the M.2 2280 slot, but it has no heatsink and runs hot. Most laptops cannot cool a Gen5 drive, so the T500 is the safer pick.

Do they last the same?

Yes. Both are rated at 2,400 TBW and 1.5 million hours MTBF, so endurance is not a reason to pick one.

Do I need a new motherboard for the T705?

Yes, for full speed. You need a board with a PCIe 5.0 M.2 slot, typically Intel 13th/14th Gen or AMD Ryzen 7000 desktops. It still works at Gen4 speed in older slots.

The T500. Gen4 drives draw less power, and this T500 ships with a heatsink, while the T705 is a bare drive that relies on your motherboard's M.2 heatsink.
