I had the same experience with the first few oat milks I tried, but after trying a few more, I found a couple I really like that come the closest to mimicking half & half of any non-dairy creamer I've tried. I quite like the Chobani Extra Creamy and recently tried the Planet Oat Barista (when I couldn't find the Chobani) and really enjoyed it. They're both full-bodied and have a good mouthfeel. You'll still get that slight hit of oats, but I find it isn't as distracting when the creaminess is correct. Most non-dairy milk alternatives are just too watery to be enjoyed in coffee.
