Hello, which camera do you use? Which is the best? I don't know what to buy. What about huawei 20 pro 40MP camera?
First part - it all depends where I am and what I'm doing but anything from the whatever it is on my phone, through action cam, ruggedised compact, dSLR to a large field camera.
The above sort of answers the second part - there is NO 'best' in terms of this brand or that brand.
The best camera is the one you have with you.
You don't need to spend a fortune to take good photos - most of what makes a good photograph is the light, your eyes and your brain. You asked people to look at the ones you posted - most people would prefer verticals and horizontals to be correct. You could easily have taken the same with pretty much ANY camera whether it be a £5 disposable or £5000 model.
IF you decide to move towards equipment with more features then I'd suggest you at least aim for something that has a tripod mount...you might never use it but in low light a tripod will usually allow you more options with lighting.
