Which straightener is better? the chi ceramic flat iron or the solia tourmaline ceramic ion flat iron?

im buying a new straightener and don't know which one will work better for my hair. i have very frizzy, thick, curly/wavy hair that usually takes about 30 min to straighten and goes back to my natural hair as soon as i walk outside (I live in the south and it is very humid). im looking for a straightener that will be quicker to use and last longer even in the humid air.
