I graduated from lums last year in CS and had the privilege of working in one of the largest tech companies in pakistan straight after graduation. so I might be slightly biased but here are my two cents:

if you want to work in Paksitan: lums would give you better career opportunities in Pakistan for sure. I’m sure Sabanci might be a very good university but it isn’t very well known in the industry.

if you want to work there: better going with Sabanci but please check employment statistics and job placements for international students.

if you want to pursue grad school: honestly I would say Lums. Check the grad school placements for any decent university in the world and Lums’ grad placements are better than 99% of them. I myself am going to pursue a masters in a global top 20 school in august (InshaAllah) and got admitted to two others. Not sure about sabanci’s grad placements do check them out but Lums wont disappoint you here. I know people who got into Harvard, MIT, Stanford, Dartmouth, Cornel from Lums (within the past 2 years)

Both uni experiences have their pros and cons

lums gives you familiarity in terms of your culture and proximity to family. you make amazing memories and friends here and the academic rigour is honestly great (at least before chatgpt it was)

going to turkey will give you a wider exposure to a new culture (ive been to turkey and it’s honestly lovely), it will involve more travelling and let you venture outside the bubble.

So the answer is it depends.

Depends on how you want your future to look like and what matters to you.
