I also like siphon feed brushes, for various reasons. I think all the major brands have good stuff. I personally like Badger. My SA 200 is well over forty years old and going strong. It is my go-to brush for everything except when I really need a DA brush for very fine lines, like Italian camouflage. For a DA brush I have never heard many complaints against the Badger 150, my DA brush.
For a first brush, don't worry about what is best. Until you really get experience you will not be able to pick the right criteria as far as defining best. Get one that works well and use it for a few years.
One big, important thing- do not take a new airbrush out of the box, mix up some paint, and try to paint a good model kit. Airbrushing takes experience. Spend at least an hour of actual airbrushing time painting scraps or junk model parts.
Also, the choice of a compressor may actually be more important than what airbrush to get!
