Nothing will go without criticism from someone. For example, I personally did not enjoy Destiny or Destiny 2. Does that make these levels bad? Far from it; they just did not appeal to me, whereas they may be other people's favorite levels.
That being said, you shouldn't always ignore criticism. The best way to handle a comment such as "the PSP side sucks" is to ignore it, but there is such a thing as constructive criticism. If someone tells you that the visuals in your level could use more polishing or maybe some more stickers, then you shouldn't let that criticism get you down, but use it to be better in the future.
