Honestly, depends on what you want from it and what part of the world you live.
There's work horses
There's fans for reduced noise
There's mixed flow for a bit of both.
EC motors for speed control..
Really does depend on what your aims are.
I've had fans like ruck , German made, Swiss bearings, seen 10 years of constant use and still working for second and third owners years after, 24/7 use. But are they quiet , are the fook.
But they run smoothly, perfectly balanced and shift air very well
