I am curious if the preference for double pointed or circular needles is related to the knitting style.
When working in the rounds, I prefer:

Define Continental knitting style. Knitting with the yarn feeding through your non-dominant hand. (Left hand only if you are right handed).
I started with crochet. When I learned to knit, I choose to keep the yarn in the same place while learning. Later I also learned to hold the yarn in my right (dominant) hand for two yarn fair-isle.
I choose to knit Continental style because it seems like both hands have an equal share of the work.
I learned to knit in the round on double point needles. I did not like the many points poking me while I knitted.
I also find the thin cord of flexible “circular” double pointed needles helps me keep tension between needle changes (since I often use two “circular” flexible dpn’s at a time).
Ridged dpn’s felt like knitting with a porcupine and left me with stretches between needles.
Flexible dpn’s helped me avoid both those problems.
But I have also learned to hammer nails with my left hand when they are to the left side of my body. Sometimes you cannot safely twist around or lean to get your right hand to the nail.
I learned knitting, as an adult, some years ago. My first goal was to be able to knit socks. Because I learned knitting by watching youtube and most videos are English I begun my first sock as a thrower. Halfway through the first sock I naturally switched over to the Continental knitting style and there I have stayed.
I have tried all possible systems for knitting socks and mittens in the rounds (Both 4 and 5 DPNs, flexiflip DPNs, short circular, two circulars at the same time, magic loop) but I always go back to 5 DPNs. That is my preferred way of knitting in the rounds.
It a bit surprises me how few actually vote. We have at this moment 76 views of this thread, but only 6 votes, nothing to have any statistical significance.
I knit Continental style on everything, because it was easy for me to learn compared to English.
I also knit on double-pointed needles when knitting in the round; I have learned to use circular needles, but so far have only used them for making baby blankets.
I can knit both methods and any needles. My preference is english and a long circular for magic loop. I taught myself continental for things like ribbing though.
I started to knit for the same reasons, socks. I crocheted for years so trying to knit English style felt too clumsy for me. Thankfully I found this web site and discovered Continental knitting. I use my circular needles for everything. Once I learned magic Loop I gave my dpns to a neighbor along with most of the straight needles I had.
BTW I voted 
I’m with GrandmaGrizzly - circulars for everything! I have a set of Addi Click for both turbo and lace. Can’t imagine using DPNs again. I did try once. Too many ends poking me. So I learned magic loop.
I knit with circulars all the time, but do occasionally use DPNs, like at the top of hats. I like the look of the flexible DPNs and have enough Denise tips and 3" cables to make my own - fewer pokey needles.
I am a self taught, learned long before computers, I had no one to teach me and the booklet I learned from did not show how to hold the working yarn. I guess I am a thrower. I actually take my right hand off the needle to wrap the yarn around the needle.
