Even though Mel Blanc did over a 1000 different Voices, other voice actors are the most impressed by this

Again, it's similar to what Blanc did. On multiple occasions, she had to play a character impersonating another of her characters all while interlacing with a third or even fourth character that she was also playing. They all had different voices, different mannerisms, different looks. But when she was impersonating, you could tell which character she was playing and which character she was impersonating.

She's received high praise for her performance from almost everyone. She not only played about two dozen characters, often interacting only with herself or multiple versions of herself, but she made each unique and still managed to blend them together as needed, like Blanc was able to.
