It really depends I prefer powder I got plant spirit because it was so reasonably priced for a kg and shipping.
I guess capsuals would be more convenient if you want to put it into drinks you need gelatinized I dont i have whole herb powder and I bake with it because I don't like the taste alone I have added it to all kinds of cookies peanut butter or spiced were best I also liked it in a spiced banana bread or brownie.
So you need to think how you want to use it to know shock to buy.
