I’ve had the opposite experience between Logitech and Razer, at least when it comes to mice. Every modern Logitech mouse I’ve had (3) has had the right and left click switches replaced as they started double clicking right after the warranty expired.
Logitech are actually using the wrong switches as they’re running them below their design voltage and is causing premature failure. I swapped them out with appropriately rated switches and they are still in service, now for much longer than the original switches.
When the failure started though I switched my main mouse to a Razer with optical switches and have had zero problems with the hardware. Software wise, Polychromatic + OpenRazer on Linux works better than Razer’s software on Windows. Razer’s software leaves a lot to be desired, but Logitech’s software is only marginally better.
If you can afford it, Honeywell PTM7950. It’s very stable and avoids pump out, which is great in a laptop where you don’t want to repaste very often. It’s a phase change material, not a standard paste. To apply, put it the fridge to cool. Afterwards, cut to size and put it on. Once it warms up, it liquefies to fill all the small gaps.
Otherwise, most other pastes are fine. I’m partial to Arctic MX-4 but they’re all pretty the similar. On direct die like a mobile chip I would recommend spreading it out to ensure even coverage as gaps can cause hotspots which may eventually damage the chip.
