Stern no longer gives full scholarships- they give $10-25000 depending on scores and when you apply. They have a big commitment to financial aid, but non-FA merit money is dwindling.
I go there and it’s a great school- I really love it. I also have friends who love Touro. I’m currently a bio major and I chose Stern for that reason- their program and guidance are top-notch. For other departments, Touro can easily be just as good. There are pros and cons- Stern is more rooted and has more amenities but Touro has more cash flow. One is bigger (though nowhere near huge) and one is smaller. Both are very yeshivish-friendly, but one will have a much larger yeshivish population, which makes a difference to some people. Both will have class material which may be objectionable- PLEASE do not think that because you’re going to a Jewish college, and kal vachomer Touro, that everything will be al taharas hakodesh. My Touro friends complain all the time about extremely inappropriate things they were forced to read in English classes.
YU in general is very easy to get into because they see themselves as a flagship MO institution and therefore want to attract as many such students as possible. To get into honors is harder, but no, it’s not nearly the same level of difficulty to get into as Harvard. Almost no schools are as difficult to get into as Harvard. (Though my friends at Harvard tell me that while there’s a lot more pressure there, they don’t believe that the classes themselves are more difficult there than at other colleges. They feel, after sitting in on classes in other schools, that the classes are equally rigorous. And my friend at Barnard who takes Columbia classes finds them not to be more difficult than how I described some of my current Stern classes.)
