With powders, you really do need to just experiment until you find one that works for your palate. I used to use a Living Harvest hemp protein that was pretty neutral - but like the others above, I found that while I could eat whole hemp seeds without issue, the isolated protein didn't sit too well in my stomach.
I just use the seeds now - and in soups in particular, they work really well. Is is true that you'll need to pop the broth+seed part of the soup in a blender to emulsify it, but that takes just a second - and you are good to go.
From a nutrition standpoint, I think there is something to think about with regards to isolates - regardless of the source. They have their place - for sure - but if you can avoid the processing and go straight to the actual food - my own feeling is that I get more of the total nutrition and fats than *just* the protein hit. (but I'm also not a strength/body builder dude :^)
(and full disclosure - "I don't always use powders, but when I do, I prefer Vega Natural." )
So start tasting - you'll find one that works for you.
