When I first started knitting, I used whatever was at hand, which was those *lovely* metal needles (Susan Bates?) that everyone has lying around. Once I got more serious, I was in college. Therefore, I had not much money, but a great want of a large selection. I bought from eBay several collections, all bamboo- circs, DPNs, and straights. They were adequate, but really horrible needles.
As I progressed, I started buying Addis in the sizes I needed for current projects. Then Addi Lace.

In the meantime, I bought some HiyaHiyas, and quickly realized that I prefer them to Addis. Not only are they less expensive, but I find them more pleasant to use.
In terms of straights vs. circs vs. DPNs, again I started with what I believe is most common- straights. At some point I began using circs, even for knitting flat. I think I have one pair of straights in my apartment now... a pair that came with a kit. They are lovely wooden needles, but after finishing the sweater they came with, I'll probably give them to my younger sister- I'm just not a straight fan.
Both Babies! Such excitement outside the window-- perhaps a bug?
And last week... Oh, last week I discovered 4" DPNs!! (Well, I've known of their existence, but last week I used them for the first time.) AMAZING! It makes doing the short fingers on my sister's fingerless gloves so much easier- less excess needle waving about, causing problems. Life is good.
In summary, brandwise my favorites are Holz and Stein, but for reasons of practicality I usually use my second favorite brand, HiyaHiyas. I use circular needles for most everything, but DPNs for small-circumference knitting (unless it is stranded- then I like magic loop.)

(Photos of kitties added to enliven the post. Since, you know, needles are so super exciting and different... also, I don't have any photos of them handy, and the light isn't great, being as it's night.)
