I'm going to be garaged. Thats the problem with stuff in today's day. There is always a new and improved product so what you had was good but now there's something even better. Hard and expensive to keep up.
Just like everything else, buy what is good and cost effective now, and be happy with it. People absolutely LOVE Seal and Shine (you can find almost every YouTube detailing channel saying its praise for it), so if I were you, go that route. Just make sure you read how to properly apply it. Some people apply it while the car is still semi wet, as the product can streak if not properly applied (100% reversible though, just time consuming).
