Hey!
I did revs in high school and now major in history at uni, so I am pretty biased in favour of history haha, but for what it's worth, here's some of my thoughts:
When I did revs, I studied France and Russia. Both were super interesting, but Russia was definitely my favourite. When i started revs I didn't know anything about either revolution. So even if you don't think you'd be interested in Russia or China, you never know! Now in uni I continue learning more and more about the Russian rev and I find it all just so interesting. I'm not sure why I like the russian revolution so much, but maybe because it happened in the 20th century so it feels more real/ the impact of the russian rev is still like very relevant today.
The Chinese revolution also happened in the 20th century, so if you think you prefer modern history, then you should enjoy the unit!
Meanwhile, the French and American revolutions both happened in the 18th century. I still really liked learning about the French revolution, but personally, i found it a bit difficult to visualise the events actually happening. There's nothing wrong with that, just saying that's possibly why I personally didn't enjoy it to the same extent as I did Russia. However, if you think you prefer more distant history like this, then maybe you won't enjoy doing Russia and China.
I never studied philosophy in high school, so unfortunately I can't give any insight into the merits of doing philosophy
Revs is definitely the best subject I did at high school. In fact, it's the entire reason I ended up going on to do an arts degree and major in history. It's difficult (i've especially heard that the Chinese revolution is really tricky), but it was so beneficial to do, you learn sooo much about each revolution. If you're thinking of doing an arts degree, revs is structured very similarly to how history is taught at uni, in terms of the types of assessments you do and the workload. In fact, revs is probably the same level of difficulty as a uni subject. If you want a challenge (that's also super interesting!) then I can't recommend revs more. If you're looking for easy marks, or a light workload, then you probably shouldn't do revs (I guess it depends on what other subjects you're doing, because revs really requires a lot of time). However, in saying that, I'm not sure how much of a time commitment philosophy would be!
Ask yourself: why is it exactly that you would be more interested in doing France/America rather than China/Russia? The answer might help guide you towards one subject more than the other. Maybe write out a list of the pros and cons associated with doing Revs and Philosophy and see which one seems like the best choice for you. I know it's a cop-out but ultimately only you can decide which unit to do.
I'm happy to answer any qs about Revs
