Should I buy Chinese?

Nowadays there are so many companies making robot vacuums globally! It seems though, like Chinese brands are taking over the market and becoming the dominant players in the field. Everyone raves about roborock, dreame, eufy but I have read about issues with them as well. Are they that good?? I currently own the Roomba S9+.. My dad gave it to me as it was so bad Irobot sent him a free one. It's not horrible and does well on carpets but misses spots, can't find its way home, is garbage at object avoidance, and does this thing where you have to open and close the lid like 6 times before it will start. Has Roomba gotten better since the Amazon takeover? Is the cutomer service worth it? I mean they did send me a new one! I'm really trying to find the best brand in the world and buy a middle tier bot from that company. I find it strange that Roomba is now only like 1% of the market share in China. I feel like this indicates they are not that great. Are there any good brands from somewhere like South Korea or Germany? I'm really just looking for something that is good at object avoidance and vacuums well (a bin would be nice too). Lmk what you guys think!
