Try one of each for yourself! Most of what you will get is opinion based on aesthetic, in which case outside opinion will be kinda useless to you. I think the most important thing is how any particular pipe smokes for you, in your own smoking habits, with your preferred tobaccos.
FWIW, I started with a fixation on half to full bent, and am coming around to enjoy full straight pipes. I so far have bents that can hang better, and some that cannot. I have straights that can pass a cleaner easier, and some that cannot.. Mostly, I have eighteen pipes that I am enjoying the process of learning about, how each smokes and what tonaccos each performs best with. It is taking me some time, but I am enjoying the journey. o)
