More competition is good.
As others have stated, the Hasegawa Hornet may be the gold standard thus far, but not having any weapons kind of sucks. Kinetic, AMK, Great Wall, etc. usually include a decent selection of weapons with their kits, which gives us useful choices (everything from clean to loaded for bear). In comparison, Hasegawa essentially tells us to "go look in the spares box" or "spend more money on weapon sets," which certainly gives the impression that, accuracy aside, their kits provide less build freedom and less value for money.
The likes of Hasegawa and Tamiya have produced kits that have been rightly praised for their quality, accuracy, etc. But perhaps they are getting too comfortable, perhaps even arrogant, at the top. The number of properly new kits that they release per year can also often be counted on one hand. How many times have we complained about Hasegawa skimping on weapons and simply changing the decals for "new" releases. And remember how Tamiya initially expected us to buy their 1/72 F-16CJ when it was actually an incomplete product? What kind of attitude was that?
If Kinetic and co. can continue to up their game and fill out their product lineups with comparable quality kits at competitive prices, they can disrupt the market. At the very least they can cause the Japanese manufacturers to take the competition a bit more seriously and release products that are more in line with what modelers demand today. Look at how Hasegawa started to include weapons with their recent 1/72 kits.
So long story short, Kinetic is giving us another option to think about, and if it turns out to be as good as claimed, then all the better.
