I like Silk's soy creamer. Original flavor is preferable, but vanilla is still better than anything else. Starbucks' soy (they only have vanilla), Coffee mate, international delight, etc are all too sweet for me (even, maybe especially the sugar-free varieties). Oat milk is too high in sugar content, almond creamer doesn't have the right texture. Half and half or milk are okay, though I feel like it masks or neutralizes the nuttiness of my favorite roast.
I try new stuff when I can, and usually switch to something pumpkin spice flavored in the fall, but I always settle back on Silk soy creamer. ๐คทโโ๏ธ
