Is uniqlo actually good?

I've seen some good reviews about uniqlo and I've been hearing about it for some time now. But you know, it is a bit pricey (as everything now, I know) so I would like to know if the quality is actually worth the money. I'm a bit worried people just go there because of some hype.

I like clothes from second hands, but I usually don't have time and energy to go on a hunt and frankly, it's hard to find there something I actually need. Visually, clothes from uniqlo are very appealing to me because I love basic stuff and I know that I will enjoy them for a long time if they actually survive. H&m has sadly gotten so much worse recently and I just don't find it reasonable to shop there anymore, and I don't really know much about current quality of other brands. So what do you think?

Edit: I really appreciate all your responses, but I am actually asking about polish market and polish prices; great to hear that the quality in other countries is mostly satisfying though
