pleasant you mean the flavor? then kava is not really better in that way even worse, I drink mulungu and kava (hiwa med grind, nangol noble and savusavu) and yeah kava is great but for me it does "only" help with anxiety, tension and little for sleep thats why mulungu(and melatonin) is the way to go for me when I want to sleep but keep in mind that I have really big issues to sleep thats why I take so much things.
But kava works for everyone in another way so try it out, nothing to lose.
