Good replacement for KaiMatcha?

I’ve really enjoyed KaiMatcha, but I don’t know if there business is still around since support hasn’t gotten back to me. So… I’m looking for a replacement matcha. I really liked how high quality it was and how I could mix it with just straight cold water and ice cubes and it was perfect. Does anyone have any recommendations for premium matchas? I’ve done Red Leaf in the past too, but didn’t know about others I could try.

Thanks!
