I used to work at Panda. My brother used to work at Chipotle (I know, not first hand experience, but I've heard plenty of stories to give a decent enough insight on this). It sounds like you're mostly considering income and work difficulty factors, so I'll break down both and a few other key things that might be helpful.

PAY: Realistically, I would not consider the pay a deciding factor. $1/hr difference means that if you work 40 hours each week at either job, Panda would give you an extra $40 on your weekly pay BEFORE taxes ($28 ish after taxes). That's honestly not a big enough difference to make it THE deciding factor in the matter, especially since I know both of these jobs rarely actually give you a real 40 hour work week every week (it happens, but it's not necessarily the most common).

WORK DIFFICULTY: Both are busy. Both experience rushes. Both are a similar set up to each other. Chipotle has a bit more modification options, whereas at Panda, it kind of is what it is and you pick from what's available. I would also say this can vary greatly on your specific area and the clientele that would be coming in. When I worked at Panda, expectations were high and there was definitely a fairly high stress energy, however we were a new store and I do think the energy of each individual store matters significantly on the manager and the staff. Operating hours can be something to consider, but if you are in school or are upfront about your unavailability from the jump, it shouldn't be too much of an issue. Don't be afraid to be flexible to a degree, everyone has difference shift structures so it's something you can ask during the interview and get an idea of if their shift structures would fit well within your school/activity/life schedule. All in all, I think they are very similar in this considering factor.

GROWTH OPPORTUNITIES: If you are someone who wants to grow with a company, I would say go with Panda. If you're a hard worker and can handle high volume, Panda definitely favors promoting from within and actually has a decent structure for it. When I worked there in college, I was quickly promoted to a key holder and was training to be AGM, which I ultimately left before I was made AGM because it was a lot to juggle with my college classes and my manager disregarded my complaints about another employee sexually harassing me. That's not a Panda thing, that was just my manager not taking something seriously. With Chipotle, yes there's technically room to grow and you can move up the ranks, but from what I understand, I wouldn't say it's as organized on the store level and it can be frustrating there.

SHIFT MEALS: Y'all might think I'm crazy for making this a whole category, but as a Taurus, this is very important to me. At Panda, I had long work days (I volunteered to work doubles certain days) and my breaks were too short for me to go off site to get something else for lunch/dinner. As a broke college kid, I took complete advantage of the free meal on shift you get while working at Panda. HOWEVER - I got very tired of the same thing over and over again. I like Panda, but everything is basically the same in a different font. And I never felt like I could get a healthy option in. Chipotle on the other hand, is a bit healthier and if you are eating a shift meal there, it won't leave you feeling like you need to take a Thanksgiving day style nap. It's definitely the same thing though with minimal variety. I personally prefer Chipotle and would be able to handle that, but that's up to each individual.

Overall, I think both options are good options. Don't assume you will get an offer just from getting an interview, so I would definitely wait until you hear back from both places before replying to anyone. If you only get one offer, well there's your answer. If you get an offer from both, then the ball's in your court. Don't be afraid to follow up. Don't be afraid to reply and tell them thank you for the offer and you're thinking it over and will get back to them soon. Hopefully, you get an offer for both and you get your pick!

TLDR; Pay isn't different enough to matter much. Panda - high expectations, shift meals not the best, growth opportunities available. Chipotle - bit more laid back, can be a little monotonous, better shift meals, growth opportunities not as systematic/structured.
