There isn't really much difference. They came out 1% apart which could easily be statistical noise.
Yeah, that's what I read. There seems to be a big difference in terms of preservation requirements, though. Moderna's can be kept at much higher temperatures and for much longer (unless Pfizer messed up and required much stricter conditions than actually needed to preserve the vaccine).

Haven't you seen the reports of wildly inconsistent product being labeled Sputnik V? One manufacturer, every dose should look alike. Something is seriously wrong.
I have seen a claim by Slovakia that Sputnik vaccines they were given were different from those used in other samples. That would not imply the Sputnik vaccine is crap, but - if the claims are true - those given to Slovakia are probably not as good as the ones tested, and I'm not sure how good or bad they would be. As for those in other countries, well that would require testing. Again, that would not imply it's crap, or come anywhere near establishing it's crap. For all I know, the ones used over here might be as good as those tested, or worse but still far from crap. Or they might be crap, but that does not appear probable.
On the other hand, I've also seen plenty of claims against AstraZeneca, including quality issues, blod clots, among others.
That aside, the overall effectiveness in tests is higher for Sputnik than AstraZeneca so far.

Because of how little protection they provide. Amazingly, China has even admitted they aren't very good.
There are several different Chinese vaccines, and they show different degrees of effectivness in tests. At any rate, the amount of protection any of these vaccines provides against serious disease and death is usually higher than it is against symptomatic infection, and the latter higher than it is against infection. Something that makes you far less likely to die of covid without significant side effects isn't crap.
A Chinese official said they do not have high protection rates; probably that was not authorized, so nothing amazing here. It is of course evidence against them, but saying they're crap is jumping to conclusions. If the effectiveness is the lowest in known tests so far (79% against symptomatic infections), Sinopharm still is considerably better than AZ and J&J. And if it's a whole 10 percentage points lower than the worst trial results, it's still about on par with AZ (see the data in your post). Now, that might not pan out in the end, but crap level seems pretty improbable.

This leaves a bit to be desired as the yardsticks to measure effectiveness vary:
From what I read, the 50.38% was against infection, not against mild disease. Another source here
https://edition.cnn.com/2021/01/17/asia/sinovac-vaccine-asia-efficacy-intl-hnk/index.html says "very mild", but 78% in "mild to severe". This may be a case of apples to oranges, since the other vaccines are less effective against symptomatic cases.
At any rate, that's Sinovac. Let's say that one is crap. Sinopharm is a different animal. Not all Chinese vaccines are the same. Your own link shows an efficacy for SF greater than that of AZ and J&J in trials so far. Granted, that is preliminary evidence, not conclusive. But it certainly is not evidence that SP is crap.

As for declining a vaccine: The only one of these I would actually decline is Sputnik V and that's because I don't trust that you're getting what you're supposed to be getting. All of these are far better than nothing. Sure, there's a slight risk--but that's nothing compared to the risk of Covid.
But again, the risk that the Sputnik vaccine would be bad and significantly hurt you (you don't see people getting killed or seriously ill as a result of using it, right?) is almost zero, whereas the probability that it will provide a good degree of protection is high. If people here did what you would, we would very probably have more fatalities, though it's unclear how many more; after all, there are still too few Sputnik doses anyway.
By the way, the vaccines that are sometimes available here (now they're out, it seems, but eventually more will come) are Sputnik, AZ and SP. People who qualify to get one cannot choose which one, and probably most people will not be eligible for any of them for a long time. Eventually, if the Sputnik vaccines begin to be produced locally - partially at first, completely eventually - (and that's a big if; that's the plan, but plans here often fail), I might have a chance of getting one (there is a good chance I'll get infected before that happens if I didn't already, of course, as it's likely to take a very long time). Getting a Sinopharm or AZ seems considerably less likely, though it might happen. The rest are completely out of reach.
