Raven Tools is great for that

Well I actually don't use Raven anymore (though I would like to) because I was ending up with too many memberships and software subscriptions, etc... and I couldn't afford it. So the choice was clear and simple, SEOmoz membership wins hands down, every time!

The thing Raven does have though is the project management side of things, and the link management... the link management IS the best feature in my opinion... and at the same time, the only thing lacking from SEOmoz tools (it would need to be similar though to the Raven Tools one if they made it though as that was really well put together).

You get tonnes more from SEOmoz than you do Raven... this community for a start! lol

I learnt literally every last thing I know about this stuff from following SEOmoz's stuff. When it comes down to it, knowledge is more important than any tools, and knowledge is what you get from SEOmoz.

Righty... in the interests of defending my original position

I've looked around a bit, and granted not all of these are credible sources but again Todd Malicoat is as I'm sure you'll agree. Jill Whalen in one of the below links says she'd prefer them not to match and the others are people of whom I don't know their knowledge or experience, but (and admittedly this is hearsay) one guy says he heard Matt Cutts at PubCon say they should be at least a little different.

One guy (again I don't know how credible he is as a source) said he tested it and found it can be found as more spammy if they're the same.

Anyway, it appears this debate has happened before in other places and there are some good points made, so here's the links

Over all though, I think we need to know if the test Rand and Todd spoke of ever happened, and if so what the results were.

Haha, yeah Matt should be a politician

You'll probably get some complaints by blog owners, and it really doesn't do a lot anymore anyway. Most of the links will be either removed fast, the ones that stay will be on blogs that aren't maintained and are therefore full of thousands of other spammy links for Ugg boots and viagra, and the rest will be on blogs that are both irrelevant and practically worthless in terms of what it will give you.

You could always just find a few decent blogs that are dofollow, give a good response and add the link yourself More likely it will stay that way.

A bit of each if you're limited like that... if you've already got the A grade for the keywords then I'd focus on link building mostly. Maybe an hour on the on-page (as long as your content is right already) and the other seven on links?

You'll still need to do more later though.

Totally agree with Alan, it can cause circular navigation problems for crawlers too.
