Need advice for starting with a 172 or 152

So I am a freshman in college and my ultimate goal is to make it as a commercial pilot. I was planning to attend Embry Riddle this semester but decided to defer a year to save money and acquire my pilots certificate locally around me where its cheaper. My question is whether it would be worth the extra forty or so on every lesson to fly a 172 over a 142? Keeping in mind where I want to go, would flying a 142 hurt me overall financially and/or skill wise?

Thanks
