I don't think there was ever a US squier, and the Mexico were Fender, made with squier parts (squire series).
I've owned mij, mik, mii and mic squires. It's all down to quality control, some years were better than others, this is what you need to look out for. Early and mid 80s jap squires are rated by many as good as US fenders. I owned an 89 p mik and it was great, couldn't get on with its glossy neck though. I recently had a 2010s affinity p bass mic and it was amazing, fairly light and sounded really good fully stock. So much so, I had to take it apart to try and work out why it sounded as good as it did. I now play SS basses, otherwise it was a keeper.
Some CV and VM squires are excellent basses in terms of build and sound, some are not as good. Because quality control varies, even from the same batch, you need to try a bass (or any instrument for that matter) and some will feel right to you, others won't. There isn't one size fits all.
