Audio technica at2035 vs at2020?

I'm just starting out and I plan on getting the blue icicle xlr converter for the mics. But I don't now which is better the at2035 or at2020? Whats the difference? and I can get the at2035 for 90$ but idk about the at2020 are there any other good models for starting out? And also I do rap vocals so yeah
