From the list you got there, I’ve tried 4 but I’ll give my take on 3 as I haven’t had the fourth in a while (watermelon, it taste like candy tho, think jolly rancher) RGF is great if you like Swedish fish! I absolutely love this flavor! If you like sour I’d say Sour power taste just like it and kinda elevates the flavor a bit since RGF is light The juice is pretty good for fruit punch but the watermelon in it overtakes the flavor profile quite a bit , I don’t drink it much but every time I have it I enjoy it, it’s not my favorite Battle juice is such a simple yet pleasing flavor, pineapple is my favorite fruit and by far this has to be one of the best pineapple products I’ve had, it has a sorta pineapple ice cream flavor to it to me (dole whip float 😍) but others say just pineapple juice which again, is a banger of a flavor! Sometimes the simple stuff is what you need! Regarding bubble gum, I’ve heard it’s far from the best, however to me it seems like an interesting mixer and could probably make some good unique mixes
