If you already own the license then yeah install it and play with it again, but I wouldnt buy it today expecting the 2010 magic back.
For me its still useful as a dirty workbench... clean/merge lists, remove dupes, test proxies, scrape sitemaps, pull titles/meta, check links, quick footprints etc. The actual “hammer Google all day and pull millions of urls” thing is mostly dead unless you throw proper proxies/apis at it, and at that point other tools make more sense.
Also footprints for expired domains usually means finding old indexed pages by niche/CMS/platform patterns, then checking if the domain is dropped/redirected/available/has links. Not whois stuff. SB is still pretty fast for that first messy discovery step.
