I have a device that charges using a USB-C cable, and I'm wondering if I should use a cube charger or just plug the USB-C cable directly into the USB-C port on my surge protector. Which option is better for charging speed?

If your device utilizes PD, then go with the cube charger. It generally provides more energy than built-in ports on surge protectors, which often have limited power output. Also, if I don’t need a fast charge, I’d prefer a lower wattage to prolong battery health; my phone charges fine overnight on a basic USB-A charger.
The choice doesn't matter too much unless you need a quick charge. As noted, the USB-C port might be slower. Choose whatever is easier for you!
Most modern USB-C devices support fast charging through a technology called Power Delivery (PD). The cube charger that comes with your device is likely optimized for fast charging. The USB-C port in your power strip might not deliver as much power, similar to older USB-A ports, leading to a slower charge. Check the specs of your power strip to see its power output compared to the cube's—if your device supports PD, the cube is your best bet for speed!
Look at the amps on your cube and the surge protector's USB port. More amps equal faster charging, but fewer amps can be better for battery longevity. Your device should manage the amperage to avoid damage, but it's something to keep in mind.
Your cube charger will typically charge your device faster. Check the wattage on the cube—anything above 25-30 watts is good. Meanwhile, the USB-C port on your power strip is likely around 20 watts.
Thanks for the clear explanation! This helps a lot!
