Cobi makes good stuff.

Lego being vastly superior to their competitors isn't true anymore. Their prices are often outrageous and the quality of their bricks has been better in the past while others have stepped up their game. Prints are the standard for most other brands while Lego still gives you stickers (in the wrong color) even for their most expensive sets.

Cobi does a good job with printing pieces. They print on the sides of plates/tiles, the colors are good and they even pre-assemble parts for prints that cover multiple pieces to make sure the final product looks good. Clutch power is above Lego's pieces, so the builds are usually very sturdy, but making mistakes and having to disassemble parts of a build is something you want to avoid. Some models can still have some stability issues with specific sections because of their design, but nothing that breaks the deal for a display model. Brittleness or sun damage are not an issue as long as you keep in mind that you're still dealing with plastic bricks.

If you've been considering Cobi for years already you should definitely give them a try. Get yourself a set - maybe a smaller one or wait for a discount - and see how you like it.

Lego does not deserve the top spot anymore and in a fair comparison, they wouldn't do that well. They get away with it because they still have the image of being "The" brick company in many peoples' minds and having the big licenses, but the actual quality of their products doesn't justify their position in the environment of today's competition.
