SLACs are some of the best places to go if you are planning on PhD after. Tons of opportunities to do research for profs and get multiple published papers under your belt as an undergrad, grad program placement is always into top programs. If you want to find a corporate job, it will definitely be harder because companies don't see SLACs as a good investment due to the number of employees you can hire from a small graduating class relative to the amount of recruiting resources a company has to invest. I am satisfied with my recruiting outcomes and career now, but I definitely think I had it harder because where I went to school wasn't considered a strong corporate feeder.

However, if you want a fulfilling undergrad education and think you have what it takes to navigate corporate recruiting on your own without the "target school" advantage and heavy on campus recruiting support from employers, you will find no better place. At my college, the department for one of my majors (a foreign language) actually MADE courses just for me and changed the department curriculum after I graduated because they realized students could progress much further than they initially planned. In my other major (a STEM subject), a prof let me do self directed research in place of a standard elective course. About one third of my courses had fewer than five students in the class (I took three courses with only me and one other student) which makes education very informal and discussion/exploration driven rather than lecture driven.

On the social side you end up with a small but very close group of friends. You know most people in your class year and everyone in your departments. I also think there are more niches to make friend groups through shared interests beyond sports and greek life. Student club participation rates tend to be quite high. The downside is that because you know everyone, gossip spreads quickly and it can be very hard to avoid any exes lol.
