The thing is that, I too think like you. Even I prefer working on a website since I do not have to install another app to slow down my phone. But, I am a digital marketer and thus far my research has shown me that people have started to prefer apps over websites. That’s why Google is doing everything to better develop PWA.
Moreover, we search apps which we use once a day or very few times a week. Because we do not place these type of apps to the homescreen.
But, apps like Social media or PWA from discourse which people visit more often in a day, they place the app on the homescreen where they do not have to search that app. They just open the phone, tap on the app and that’s done.
Although, I’ll still repeat myself, all of this is for my industry. The research is for my industry, different industries will have different people with different taste.
