Those two eyepieces are probably from the same factory.
This is my non-expert view of how this works, gleaned from hearsay I've read:
What tends to happen is that a Chinese manufacturer, such as Long Perng, makes a lot of eyepieces. Then, resellers will pay for some of these eyepieces and to have their names printed on them.
In any manufacturing job the quality of the results will vary (this is true for many products). Generally speaking, the resellers who pay more money will get the best eyepieces. The ones who pay the least will get the worst.
This is somewhat reflected in the prices of the eyepieces offered by resellers.
The big-name brands that I can think of who design their own eyepieces are APM/Lunt, Baader, Explore Scientific, Nikon, Pentax, Takahashi, Tele Vue, and Vixen. Generally, anything that costs 150 €/£/$ or less is going to be a generic model which then gets a brand name stamped on it, like Altair, Astromania, Bresser, SVBONY, Meoptex, OVL, Celestron, Orion, William Optics, or many other names.
There's quite a range of prices for what are essentially the same eyepieces.
From what I read in astronomy forums, SVBONY are currently building a name for themselves in the low-budget end of the market. People are generally pleased with the quality of their products, and especially pleased with the prices of their products. You have to do some research before buying, though, as there are a few items in their line-up which have been badly received.
