Let me know which and why?

Maximum users have chosen the preconnect option.
But now should I only preconnect the page2.adsbygoogle.com url which comes by default when we apply for Adsense or should include these g.doubleclick.net adbygoogle.com and others also.

Do not abuse preconnect it may affect negatively for slow connection users.

I have used and found this makes ads loading faster.

Almost now all people using Jio 4G in India and internationally 5G, I think

If you’re getting best Internet in your area, you’re lucky one out of 1000s people.

Many villages yet suffer from slow Internet and poor coverage. They are one who feel the real pain by suffering from ping loss, high latency, slow download and slow upload speed.

Speaking in general, in coming days 5G may be reason of slow Internet. As greed will increase, Dev will push more scripts with assumption of fast Internet while forgetting slow Internet users.

@GulshanKumar How Preconnect will help if I am using lazy loading of these Adsense scripts? (Load on scroll) As I understand, even though you preconnect, it will load while the page is loading and ultimately, it increases page load time.

For Lazy Loading, it doesn’t make any sense. Preconnect is useful when you want something to load early.
