Trunk comparison: Peugeot 3008 vs Skoda Kamiq

Key Differences (highlighted: >10%)
The biggest differences concern the usable cargo length with the first row of seats upright, the vertical depth of the trunk, and the loading edge height. Specifically: The Peugeot 3008 offers a trunk that is 9.8 in (34%) longer with the first row upright than the Škoda Kamiq.
The Škoda Kamiq has a 2 in (45%) greater depth between the loading edge and the trunk floor. The loading edge of the Peugeot is 3.9 in (14%) higher above the road surface than that of the Kamiq.
Impact on Usability
The longer cargo length of the Peugeot (with the first row upright) makes it significantly more suitable for transporting long items when the rear seats are still occupied (e.g., slats, skis, long boxes). In situations where cargo length is needed along with passengers, the Peugeot is more practical.
The considerably greater trunk depth of the Kamiq means more vertical space behind the loading edge. This is advantageous when volume is used in depth or when transporting bulky, stackable items.
At the same time, a deeper loading floor often requires more bending when loading and can be less convenient when accessing the trunk interior.
The lower loading edge of the Kamiq makes lifting heavy items into the vehicle and sliding boxes or luggage rollers inside easier; the 3.9 in higher loading edge in the Peugeot makes loading more strenuous but is less relevant for very long cargo as long as the cargo length is sufficient.
Other differences (e.g., +5.5 in (9%) longer trunk with folded seats in the Peugeot, +2.4 in (8%) higher opening height of the Kamiq, or ±0.8 in in narrowest width) are small and have little impact in everyday use.
Conclusion
For users who often need to transport long items without folding down the front row, the Peugeot 3008 is the better choice. For those who value deep, stackable cargo space and easier lifting of heavy loads, the Škoda Kamiq is more practical.
