(I'm shorter and heavier than Arkan oof (I'm 158-161cm and 70-80kg), not sure how I compare to Apple cause Apple didn't put measurements.)
Apple may have slightly higher AP and LS/SS given feats (punching a hole through a door in particular, but this would depend on the material of the door), but Arkan is still close enough to make it negligible in difference and has likely MUCH better skill in leveraging his AP and LS/SS given combat/martial arts experience and fitness (overpowering people much heavier than him who are also about as heavy as what Apple carries in addition to his own weightlifting) also due to feats.
Apple probably has higher durability and pain tolerance despite AND due to dealing with chronic fatigue and poor health conditions on top of withstanding feats such as closets falling and blows with bricks but Arkan has higher stamina and more combat experience and so is likelier to be able to tolerate and know how to mitigate actual combat damage. (Arkan, by hitsticks did you mean batons or martial arts sticks in martial arts like FMA/Kali/Escrima/Arnis, Silat, SCA (Society For Creative Anachronism)/historical combat re-enactment like HAMA (Historical African/Asian Martial Arts) and HEMA (Historical European Martial Arts), other weapons-based martial arts?)
Arkan should have higher speed than Apple (I know walking pedestrian traffic light walking timers can vary between 10-30 seconds while switches from the red light to green light take 3-5 seconds and green light to red light take 5-7 seconds in Singapore at least, and it would very likely depend on which region and country one is in for sure).
Arkan's intelligence should be higher than Apple in general overall despite Apple being better in certain areas like languages and linguistics, though to be fair Apple also has had higher education overall than Arkan so possibly Apple also knows more or has more academic material/topics to refer to and learn about on a regular basis compared to Arkan (this IS where age would play a factor), though then again, both of them also could generally learn stuff both within and beyond their academic level from the Internet or other sources beyond academic material as shown by Arkan using college-level textbooks at a young age.
