Premium Cola!
Afri Cola, Fritz Cola and Vitacola all three awesome and from Germany. Don’t know if they’re available outside Germany though, if you find any give em a shot.
The Danish cola.
Unironically, Lidl’s “own brand” Freeway cola is p alright, I’ve never felt much for buying, and paying extra, for name brands.
All my fat kings drink RC
Have you tried https://fritz-kola.com/en ?
In france I’ve found carrefour cola to be an okay replacement, but would love to hear better options!

Ok, I’ve got to promote Austrian lemonades from Murau, called Murelli, at that point - and their beer Murauer is really delicious btw
Not only has Murelli an alternative to Coca Cola, they also feature a really good orange lemonade (instead of Fanta) and if someone is a fan of ‘Almdudler’, their ‘Alm-Rausch’ is imho better than the original.
Here is the catalog of their offerings (although in German and I couldn’t find a translation)
