Well, that's a pretty normal problem, honestly. I went through exactly the same thing and wasted way too much time opening twenty tabs like I was doing scientific research. What helped me was sticking to review sites that explain why they rank casinos instead of just throwing stars everywhere. Around the middle of my search I found www.top-casinos.com.de and I liked that it compares important things like licenses, payment methods, game selection and bonus conditions in one place instead of making you dig forever. I still double-check a few details myself, but it definitely cuts down the guesswork and saves a lot of time.
