You have titles here that actually perform tasks and automation and titles that do nothing but monitor and report.
If you are paying for your software - and you really should be if it makes you money, Market Samurai is definitely the best value out there. There are some features that I never use like the content finder stuff, but for quick competition look ups, its great. The guys who make it are always updating it and the community of users is active in sharing innovative ways to use the info that you can gather.
IBP is OK for making huge reports for clients who are impressed by size over substance. Unless IBP has made some big changes in the past year, its bloated and outdated and works on a page level so its useless for big sites. Again, maybe its changed recently but I wouldn't ever pay for it.
Scrapebox kicks ass and can do some really powerful stuff, IMO its the LINUX of the tools - not pretty but doesn't give a shit because it gets the job done. The price is more than reasonable for everything it does.
I used to love SENuke but the big build up to SENuke X turned out to be lipstick on a pig - it is still based on outdated methods. I was a paying member for a long time and loved the account setup features and captcha solving, but thats not worth $97 a month. They are shady anyway, they owe me a measly $350 in affiliate commissions from a single referral (according to their stats), that I discovered when I logged in to checkout SENuke X. I contacted them repeatedly but they have never responded to a support ticket - Areeb finally answered a PM implying there was some kind of fraud, which is complete B.S. In the past 2 years I have probably sent them over 100 paying customers simply by word of mouth, so now I have no problems chiming in to tell people not to bother paying for it. Trying to explain to a client or company that you are using a software title with the word NUKE in it is always fun too.
The value in SEOMoz is not in the online tools, but more so in the community and information. SEOMoz does have some cool tools for research and campaigns, but I think its over priced (I do pay for it anyway). I think SEOMoz is kind of the IPhone of the SEO community - all the cool kids have one.
I am still a fan of Raven and have been with them since the beginning. They have good support, the reports are nice, re-branding and white-labeling is nice, plus the grandfathered me in on pricing - but watch out if you go over your allotted amount of tracked keywords. Raven is a good mix between reporting, monitoring, and analytics.

The 'Suites' are not going to do anything for you but build massive reports with pretty charts and keyword tracking.
