LOR from a professor or a Non PhD project guide

[rakwad]

Hi all!

I am planning for applying for MS in CS in Fall 15. I am confused on the third LOR.
 

I can either get it from a Professor who taught 2 subjects, or from an Assistant Prof (Not a PhD) who taught a subject and supervised my final year semester project.
 

The Professor has a good research profile, but his LOR will be on terms of sincerity and my overall impression on him (He rates me as a sincere and sharp student, but I have not worked with him on any research or projects).

On the other the Assistant Prof (Masters holer, non PhD one) is not very much into research and has a teaching experience of 11 years of experience but his LOR content will be much more personal and he thinks highly of me.

Whom should I ask for LOR?

PS: Regarding my other LORs, I plan to get one from my current research advisor (I am serving as RA under him now), and my manager at previous workplace (Amazon). I am aiming top 15 universities.

In my opinion a LOR where the person writing it can go into specifics about why YOU are the best candidate for the program is much better than a letter that is more generic.  I believe that the letter's contents will matter more than the credentials of the person who writes it.

In this scenario I would say go with the latter.  Someone with a masters but can speak specifically about your work is better than a generic prof one.
