This is from my personal experience

I am pretty sure if you are into building backlinks for your website/blog, you must have got advice from loads of people that being in a top commentators list is the easiest way to get high quality backlinks. But most of the people forget to read the thin line which says that, the most of the high ranking blogs reset the top commentator plugin once a month, or sometimes once a week.

So, if you work hard for month to gain some links but loose all the links at once and at the same time google updates the PR, you are into pretty hard luck. It happened to me, I built great amount of backlinks through top commentators plugin and was pretty sure that in the next Google PR update my ranking will shoot up like anything. But then the month end came, all the links were reset and i lost around 50 of high PR link, which made my whole link building a disastrous experience.

Just wanted to warn in advance you, be little cautious while dealing with top commentators link. First verify how often the blog owner resets the links and then act accordingly .
