We own (or have a membership) in all SEO tools just to understand who is doing what.
SEO powersuite is a cool set of tools (website auditor, rank tracker, seo spyglas and link assistant) which are used as client software (not SAS). They follow different approaches and have a good understanding on SEO and how to rank well. These tools will help you, even if you have other SEO tools.
They run promotions where you can get huge discounts, for example 70% and you pay only 200 USD for their base package and you might think or have the impression that it is a one time payment. But this is not true and a subscription update is many times more expensive than to buy a new license.
Basically the bad point with them is that they cheat you with subscription updates you are forced to do to run the software. They have many forced updates, for example the cloud update or the "software Search algo updates and Maintenance plan".
To update a single product (of the 4 or 5 products they have) cost 477,60 USD for 12 months as regular price (means you have to pay 4 x 477,60 USD = 1910,40 USD for a 12 month update). The 1910 USD is just for "professional edition", on the "enterprise edition" it is probably many times more expensive. As their pricing policy is they offer some "friendship discounts" but still the pricing policy of bringing people in with 299 USD for the products and than making very expensive forced update plans is not what I prefer.
Their software is not bad but in the end you can have MOZ or Semrush for the same price or even cheaper.
(PS: You can find some of their pricing here https://www.link-assistant.com/prices.html#search-algo-updates but keep in mind that you have to buy all the packages for all the products)
