Packing cubes and compression bags solve different problems. Packing cubes are mainly about organization. Compression bags are designed to reduce the volume of soft items. The better choice depends on what you are trying to fix in your suitcase.
What packing cubes do well
Packing cubes divide a suitcase into clear categories. They make clothing easier to find, can simplify unpacking and help you rebuild the same suitcase layout throughout a trip.
What compression bags do well
Compression bags reduce the volume of compressible items. They can be useful for bulky soft clothing, but reducing volume does not reduce the actual weight of what you packed.
Packing cubes vs compression bags for carry-on travel
If your main problem is a messy suitcase, packing cubes are often the simpler choice. If your main problem is bulky soft clothing, compression may help with volume. In either case, your cabin bag still needs to comply with the airline's current size and weight allowance.
Which is better for a weekend trip?
For a short trip, organization is often more important than aggressive compression. A few well-sized cubes can keep two or three days of clothing separated without making repacking complicated.
Can you combine both systems?
Yes, but keep the system simple. You might use packing cubes for most clothing and a compression solution only for one bulky category. Avoid adding organizers merely because you have them.
