I don't think we can really answer that question honestly until Albert's reign is over and he is no longer with us, only then can we judge the scope of the man's impact as sovereign.
On that score, I think Prince Rainier III's 55 year reign as sovereign ranks up there as one of the very best, if not thee best. What he did during his reign of power is remarkable, the least of which was to marry the movie star Grace Kelly and turn everything to gold, she alone put Monaco on the map. Her presence is still felt today, most recently in the British Royal Wedding, wherein her timeless classic wedding dress was the first thing people noted when they saw Kate Middleton's.
That said, I also feel that Charles III was also greatly influential, being the original founder of the famous casino in Monte Carlo, at the same time maintaining a strong marriage, the same way his great-grandson, Prince Rainier III, did.
