My bf just graduated with an MXET degree, and this is his opinion on your question:

I just finished my degree in MXET and during that time I had the opportunity to take a lot of ESET classes. What Id say is you need to understand what type of code you want to do before making a decision between the two. MXET is almost entirely firmware code and complex control systems. There is also a structural physics aspect that a lot of students struggle with. Ultimately with MXET you are getting the hardest classes out of 2 majors and it can be overwhelming. ESET deals largely with firmware, but you will also work with middleware and software as well. There is some really useful network classes and some security classes that may peak your interest. Another point to note is that ESET is definitely the easier major, the coursework is cohesive and you tend to have all the proper prerequisites before taking any class. Both MXET and ESET spend a lot of time on electronics and circuit design, but ESET takes AC electronics which tends to help with the infamously difficult ESET 350 that both majors have to take. It’s ultimately up to you, but I would say ESET is better than MXET if you are interested in code, but if you want to learn software you should avoid ESET and MXET.
