At the time I'd have said no, she was clearly being used by Bruce to make Tim jealous which is just awful on almost every level. It was bad writing and bad creative at a time when editorial were mandating left, right and center (even though she still had some good stories as Robin).
However, now I definitely count it. Steph has stood the test of time, evolved greatly as a character, her brief stint as Robin is still referenced and it bolsters her somewhat to have that credit (though not as much as being Batgirl, which I always liked).
Bottom line; Steph rocks!
Btw, she was Robin for three months across DC not just three issues. If you're going to use her short tenure against her at least get it right.
Robin #126-128
Batgirl #53-54
Solo #10
Detective Comics #796
Teen Titans #13
I specifically remember really enjoying her in Detective Comics against Zsasz and in Teen Titans.
