Both brands are similar. Feiyu doors and windows is a brand in Guanghan, Sichuan, and later moved to Foshan, Guangdong. Currently, Guanghan and Foshan have production lines. Yibo doors and windows is a local brand in Foshan established in 2004. Its main product is aluminum alloy doors and windows.
Both brands are in the persistent development stage, and it is not enough to invest in brand operation, especially in brand planning and publicity, so is advertising investment.
For asking which brand is good, I think it depends on where you are. If it is in the western area, you can choose Feiyu doors and windows nearby. If it is in the coastal area of the two regions, you can look at Yibo doors and windows. For those who choose to join, it is better to choose the nearest one, or to choose from a few more.
