I can understand some Esperanto videos where the speaker is extremely fluent and talking very fast. If I could slow down the videos, I could transcribe almost the full thing even if I don't know all the vocabulary. That is impressive to me. There are a lot of languages that just sound like gibberish to me to the point that I can't even make out the sounds that well.
