Law school is already 3 years long in the US (after 4 years of undergrad), and most agree the second two are a complete waste of time. Other jurisdictions are different, but the US market is by far the largest.
The first year is really teaching you the lingo and how to think like a lawyer. After that it’s almost entirely electives and rarely requires hard work (Fed Courts being the exception).
I don't know why the manner in which someone studied law would have any impact on how or what they practice now. Most of the law and skill learned is by actually practicing, not what you learn in law school. Law school is about how to think like a lawyer, not how to practice law.
Pretty much any even mid-sized legal market is going to have really well-respected attorneys who graduated from some fancy top 5 law school, and some really well-respected attorneys who graduated from a local law school where they took night classes.
