I like sportea. It is one of my favorite teas, regardless of where Im at. I dont feel any sort of kick from it at all, and wouldnt call it an "energy" anything... but of course, YMMV. I just like the taste.
Never had Yerba Mate. It is not a "tea" in the proper sense. Its a totally different plant, related to the Holly. The stimulants in it are similar to those found in coffee, but not exactly the same. Anecdotally, it creates a heightened state of wakefulness, without the negative effects of caffiene i.e, jitters, rapid heartbeat, etc. If your yerba mate is causing these effects, you might look into whether or not it has been "spiked" with caffine or other stimulants in order to heighten its "energy" claims.
