They are simply different species belonging to the same genus of CAS. The former plays in the commercial SW ground, while the latter stems from the academic world, and it has been successfully incarnated in different calculators. AFAIK, no Wolfram Mathematica version is available in a calculator, is it?
Please, note I have been a Wolfram Mathematica user, and I really admire such a piece of SW. Nevertheless, saying Prof. Parisse's brainchild is outstanding would be an evident understatement, specially when you take into account its development constraints and its main purpose, mostly academic. I wish I could have count on his work during those years I spent at the university, when I was younger.
Besides, I would really suggest you spend some words introducing your scenario, before you go to the point. There are plenty of gurus in this forum (don't get me wrong, myself not included at all). They are not only brilliant people, but also truly helpful, though you might need to accommodate your wording to the western style of asking for support, since 個人淺見 I think you went too straight to the point :O) ​谢谢大家配合。
​​最后，祝大家新年快乐！

PS: I have no affiliation with XCAS/GIAC. In fact, the only CAS I seldom use now is Maxima​​​ ​​哈哈哈

I did not compare the meaning of XCAS and Wolfram Mathematica. I think the reason why it is misunderstood is that my English is too bad. I sometimes have to use Google translation, which leads to a misunderstanding of semantics. China attaches great importance to the discipline of English, but the society lacks the atmosphere to learn English. Moreover, the differences between Chinese and Western cultures are relatively large, which leads to some misunderstandings in language communication. This is inevitable and requires everyone to be tolerant. I am not malicious, I really like hp prime and XCAS, I just raised some questions. Soory my poor english 祝大家新年快乐。希望世界和平
