Sorry I didn't defined the problems clearly and thank your for your help. I am using selenium using python for web automation, not testing. The latter problem was by and large solved by subclassing WebDriverWait by adding common Exceptions related to nodes staleness. The former problem was tackled by writing a for loop detecting changes of the context to know if WebElement.click() fails silently.

The thing is I have to write these workarounds everywhere. What's more, I inject javascript code a lot to avoid nodes staleness caused by network latency. I believe selenium is not designed for writing lots of javascript. And javascript code in a string of python can not be linted, which increases debugging workload.

To this point, the cost of these hacks is too much in my project. I find puppeteer play nicely with javascript after trying. But the difference and reliability between waitFor() in puppeteer and WebDriverWait() in selenium still remain questionable.

I am wondering if using puppeteer can ease pains mentioned above.
