Where I live there are a couple of tea blenders that make various different loose leaf offerings.
You can get good loose leaf on amazon too from (e.g.) teapigs or whittard.
In my experience, the trick with loose leaf is to not to get the ones that have been ground too finely, as they make a too strong brew and the bits can pass through the filter leaving you with a dusty cuppa.
I will admit though… sometimes I want a quick tea, and I may just make a pg tips… not as good, but less faff than getting the tea pot ready etc
