Narrow bars, full integrated frames and electronic shifting are fantasy, but hey your money!

The SPEEDAO 1-piece cassette is a design that's been sold under a lot of different brands including S-ROAD and ZTTO. It's a solid unit, I've bought 3 of this specific kind of cassette in HG guise, used them for road, CX, and commuting. It's a solid-performing ultralight cassette for the price. I'll echo the sentiment that they aren't as refined, but I haven't managed to put noticeable wear into any of my units so far.

Contrary to nicklej, I actually prefer the HG design. In the XD/XDR design, the cassette is clamped to the splines (near the hub) by the threads, and all static forces are cantilevered off these splines. (you could argue that some force transmits through the sleeve, but since this is a sliding component, it will only transmit force if the cassette flexes into it--potentially causing wear and creaking)

There's also the issue that the soft aluminum threads on these XD/XDR bodies are super-fine and susceptible to cross-threading. OEM SRAM MTB cassettes are manufactured with super tight sleeves that are almost impossible to turn without using a lot of force, making it very hard to feel the engagement of the threads. I've watched a couple bodies get damaged in this way. The GOLDIX XDR cassette that I've used doesn't have this tight-sleeve problem, interestingly. 

The other issue is that since XD/XDR is a system of moving parts, arguably the manufacturing tolerances of the system need to be stricter in order for the system to work properly. The HG cassette is much simpler to manufacture in comparison. When you're buying cut-rate equipment on AliEx, it's generally safer to buy the design that has fewer moving parts and lower demands on precision.

Lastly, HG splines do not really wear with these one piece cassettes. The main reason HG splines wear is that when you use cassettes with loose cogs (and fail to tighten them properly, which everyone does), the force applied to the spline is only distributed along the width of a single cog. One piece cassettes have solid engagement splines spanning the the width of ~2 cogs on each side. This means all forces are transmitted to the freehub splines over a much wider area compared to single cogs. I've been using one-piece cassettes for around 8 years now (SRAM Red before the SROAD cassettes), all freehubs I've put these one-piece designs on look virtually brand-new.

If you don't have a pressing need for a 10T cog (i.e. 1X bike with large demands for range) I can't really recommend pushing for XD/XDR, but I also won't recommend against it.

A bad exampe could be Winspace with it's Agile frame, it is already too close to western brands and I can purchase 2nd hand SL7 (non S-works) frames cheaper in JPN.
Like the Agile frame direct from Winspace ends up to be 300.000JPY, while a used SL7 frame is ~250.000JPY. With that pricing it is rather pointless to opt for direct China frames.
