here is my personal rating of some American sodas that i know are American brands in the UK.
1. mountain dew
2. dr pepper, its kind of like coke but better imo, although we have a brand in the UK called dandelion and burdock, and thats like dr pepper and i prefer that over coke too, although id say its even 'stronger' than doctor pepper, like doctor pepper has a stronger flavour than coke.
3.Fanta, probably an unpopular opinion, but i prefer it over coke.
4. Coke
5. probably Pepsi? Pepsi is like coca cola except sweeter and 'less refreshing' for some reason? I preferred Pepsi when i was young because kids like sweet things. Coca cola also doesn't really have a taste memory for me like other drinks, i would get bored of drinking mountain dew and dr pepper much quicker than coke even if i prefer the flavour.
6. sprite = 7up? these two basically taste the exact fuckin same for me, they're like lemonade, except id probably rather just have a lemonade lol still nice though.
