My first C2C, I didn't have poles and encountered unbelievable pain in my knees during the descent. I vowed I'd never make that mistake again and purchased a pair the next week. My second C2C, I had my poles and the descent was an order of magnitude easier, with almost no knee pain whatsoever. These days, I won't hike any sort of elevation without bringing my poles. I only use them when going downhill, because that's where I encounter stress on my knees. But for me, they're a lifesaver.
If hiking downhill doesn't cause problems for you, then you're probably fine without them. I have short legs, so steep descents cause a problem for me because all my body weight comes crashing down onto my knees with long strides. With my poles, I am able to distribute that stress across two or three points instead of one, plus the added balance of always having more than one connection to the ground at any given time make them a no-brainer. I live by my trekking poles.
My first pair were aluminum ($27 from Costco) and served me well. I recently bought a pair of carbon ones because they were slightly lighter and have a little better balance. The twist-type are fine as long as you understand how the mechanism works (you should take them apart to see how everything works). They advantage of the quick-locks (at least to me) are the ability to adjust the heights while wearing gloves, but they come at the expense of added weight. Personally, I'm fine with either.
One other thing - technique is very important. You should not be "gripping" your poles. You should be utilizing the straps to make a connection with your wrists. Look online for videos of how to use them properly.
