“worth going to” can be very complicated.
One factor is cost. If you can stay at home, or with in-laws, that is a huge difference. Brooklyn Law School, plus the cost of an apartment, is probably more expensive than Columbia. Part-time law school programs are only at the lower quality ones. There are low cost public law schools, especially if you qualify for the in-state rate. The lower quality ones are often very liberal with financial aid, especially if you have a high LSAT (the trick is you’ll need good grades to keep a scholarship for all three years).
So, is a degree from a cheap law school (where only the top 10th of the class gets a respectable job fresh out the door) but with no debt better or worse than an elite law school (where half get good jobs straight out of law school) but with $200K in debt (for tuition and living costs while in school)?
Another factor is what sort of law one wants to practice. Being a prominent attorney in a frum neighborhood doesn’t require a degree from an elite law school (in any event, you start with minimal income and have to build a practice through competence and hard work). Working for “Big law” (well paid corporate law firms, in a thoroughly un-Jewish, and some would say un-Human, environment) expects one to be near the top of the class in an elite school.
And then there are people who neither know nor care about practising law, but think its a meal ticket. They are probably close to being a “shoteh” and should be encouraged to do something else.
