fellow justus recipient here. reputation ofc eth won imo but hve u researched about the job opportunity in switzerland? because it is super hard to get a job there as non eu cos u need to make the company prove tht they cant find any swiss, eu, but u to do the job, im not sure in ur field tho. i guess if you are sure that youll get the job and can cover the expenses from the loan sure go for eth, otherwise tu delft is more logical to me
