That's kind of a loaded question here.
It really IS personal preference and how much you afford.
I used the Clover bamboo when I started knitting with circulars, but then moved on to interchangeable sets so I wouldn't have to keep buying different needle sizes and different cable lengths and having a million needles. That said... the 16" clover bamboo is probably just fine for what you need now. You can think about it while you're doing that consider if you want to continue.
These are what I've used and remember this is MY opinion... yours may vary.-
Denise - they aren't bad, but I don't care for both the needle material (resin/plastic) or the cables. Many do like them.
Clover bamboo - I don't like cable
Addi Turbo - Wonderful metal needles, but expensive
Knitpicks Interchangeables - Love them! Affordable, thin flexible cables, nickel plated, birch laminate or acrylic. I have a couple sets of nickel plated and several of the wood. Great customer service.
Boye Needlemaster - Only tried someone elses once and didn't care for the needle or cable. Many do like them.
These are by all means NOT all of the choices...I just named the ones I could think of off the top of my head..
