Sure, the answer is quite simple,
Currently, TIRE 1:XDS (X LAB), PARUDS, QUICK(maybe?)
Like 3 years ago, XDS is not the same as now, because they became the sponsor of ASTANA, and they got rid of "XDS" 3 words instead of X LAB, XDS here represnts the child bikes and cheap bike(AD350), after X LAB, everthing change, absolutely TOP 1 brand in China.
PARUDS is one of the biggest manufacturers in CHINA, no doubt.
QUICK is very special, they were one of the manufacturers for WINSPACE and many many famous brands. But they do not have professional PR team or marketing team.
They are running brand with factory mindset. But still better than those INCOLOR, SEKA, X SOON, etc.
All the other brands, our opinion is if they do not sell frames for more than 2200USD or 3000USD, we will give them a shot to try, but for 2200USD or 3000USD, bruh, let them go to hell, or let the rich people take care of these brands.
X SOON is from my city Hangzhou, no real customers buying this brand, only the famous celebrity cyclists ride it because they got the frames for free.
Now XSOON is closed, they may change the name and drop a new brand next year lol.
In general, I can not really recommend, the only concern is the price, XLAB, PARUDS, bikes with correct price, but other brands, price too high, even QUICK PRO, ARONE, ERONE, now in China the frame price is like 1200USD, still too high. If you like QUICK PRO, its fine.

Can you say anything about CAMP bikes?

I also messaged them on Instagram regarding the Ace Gen 3. They sent me the geometry table, unfortunately it is partly in Chinese, but AI can translate. To me it seems to have more stack compared to the Cervelo S5. Price for the frame is quite good at 530USD without shipping. CAMP seems to focus on Chinese and south american market but probably also ships to rest of the world.

Hi received my spcycle r088 and the bb is misaligned and not straight had to ream it a lot. Could not get it to be perfectly straight and they said they are all made like that.
second problem was the di2 battery in the seat post. I had to sans down the seat tube for it to fit. Something was blocking.

How did you find out your bb was misaligned? My r088 frame just arrived and i can feel that the bb threads feel a bit rough when I go through them with my finger, also there seems to be some black „powder“ or something similar in some threads, i think its most likely from paintjob and got there somehow.
Currently i dont have the a bb here to try the threads and I will be away now for 2 weeks so i can only try after. But if my bb is also misaligned what do you do? I thought maybe just putting in the bb can clean up the threads if theyre not really misaligned, but if they are it might worsen the situation? I read that bb shouldnt really be hard to thread, at least at the beginning.

Apart from that i can say i really like the bb glossy color and the „shine through carbok look“. There are 1 to 2 little spots where the paint has a tiny imperfection (a little hole, there is still paint but a little less than around. but its really tiny, only a very small and optical thing) or where there seem to be some little scratches under the clearcoat paint.
But really overall I am very happy with the frameset and the paint. Also i got to whole frameset with the 380mm integrated handlebar. So I can also give some feedback on that after my build is completed. From looking into it I assume I will also have to sand down the seat tube a little bit.ah an yeah there is also some paint near the holes for the flat mounts, so probably will also habe to sand down a little there.
