Straight or curls

I'm back with the question as stated on my title. Straight or curls? I'm always at a point whereby idk which one to continue. I had curls for the past 3 years already, should I change back to straight and wait till I get bored of it then I change back again?

Hahah! This is my current hair. Straight and flat? Or was it bcos of my remaining curls that causes the difference to be a lil obviouse that usual? I kinda like it straight as I'm lazy to style/maintain them. But at times, straight hair can be tad boringggggggggggggggggggggg. How how?
