I found myself in the same situation, I went out and bought all the 'in' things, following guides I had seen on YouTube to the letter. Then you find another guide that said you were using the wrong snow foam, your wheels brushes were wrong and 'destroying' your paint and your sealant only last 30 days and this new one lasted 31 days . . . But the results did look good . . .
Long story short, I came down with a genetic lung condition triggered by a cold that meant these methods were no longer available to me due to the setup time, the number of the items I had to carry around from the garden, the number of times I'd need to go round the car etc. It also meant when it did become too much I couldn't just stop and call it a day mid wash. Oh, and I have 2 children, a wife and a business partner that all require my limited energy and time.
Then I came across a post on a detailing forum (which included a few of the members on this forum) about ONR and I went from there. I did my research, worked out which products would work for me within the range and 3 years later I'm still using the system. As a note, I have never polished my car and it is a daily driver in the English countryside so its paint can have quite a tough life! Is my car perfect? No, not at all. Can I tell the difference in the result of the different cleaning methods? Not really. ONR and the whole system makes the process quicker, easier and gives me results I'm more than happy with.
But as with anything, each to their own of course, as Lowejackson said, it is about finding things that work for you and your circumstances which really no one else can decide for you.
