I can look up tons of internet articles, but as with all articles, I take with a rather huge grain of salt as their motives for touting one or the other can vary and many of them just parrot each other...I'd therefore be interested to hear from those who actually play or know someone well who does and may have some insights, even tho it's impossible to eliminate subjectivity...
What I think I know so far:
Yamaha, Eastman, Selmer, Conn - still appear to generally the top quality saxes
Jupiter - maybe not quite up to the same level, but quality saxes which aren't as pricey either
Chinese knockoffs - can be had on the cheap but in this case, it's almost always you get what you pay for and is likely to be wasted money
