The first time I tried oat milk (during early covid and literally didn’t have any other choices left for milk or milk alternatives) I didn’t like it. Every time after that I’ve actually thought it was pretty good. By far it’s the best thing to put in coffee or tea, but I don’t drink those often anymore and typically I drink them black anyway. I can’t recommend brands, but I’d just say to experiment. Write down which you like. I’m sure some people like all of them, because they made it to market and I’m sure we’re tested for preference.
