It's all about precision, who is correcting the answer paper and who is using the grades/marks to do what.
Marks are supposed to be more precise but then why stop with whole numbers? Why can't we get into decimals? 98% is still less than 98.1%, isn't it?
Who is awarding the marks/grades and on what basis? For instance, in math, I could get the right answer but if I don't show the work, how much should be cut out of the max possible number for that question? Where is that defined? In science, if I don't get the definition right, but still express the idea in my own words, what should be my mark? If it is not defined, how does it matter whether it is a grade or a mark? is there a guarantee that the teacher is uniformly applying the same standard when awarding the grades/marks?
Letter grades like A+, A, A-, B+, B, B- etc can be precise too. We know what they denote. If someone is looking for a better precision then we are getting into the realm of hair splitting.
But where demand is high, admissions are tougher, because schools/colleges have to be more selective, in which case there is no other alternative to splitting hairs. It has to be done which means marks over letter grades.*
Letter grades can prove very disadvantageous too when computing the GPA. Whereas the difference between 89% and 90% is only 1%, the GPA difference between a B and a A (where a 89% translated into a B and a 90% translated into an A) could be substantial.
Both have their own merits and demerits I suppose. Tough to argue in favor of any one system.
*Editing to add that, most colleges as well as employers looking for freshmen/freshers don't make letter grades the be-all-end-all criterion for selection. Extracurricular activities like sports, leadership skills, participation in academic clubs, community service etc also carry a lot of weight. Which is why, a little difference in percentage points between two candidates shouldn't matter.
