Piosolver early 2010s version - Worth switching?

I currently own and frequently use Piosolver, the version I bought in in the early 2010s. I have a high end, 16 core CPU so all my solves are under 2 minutes. I'm aware of the advantages of the current Piosolver version (moderately faster solves, a trainer mode were you play HU hands and get real time feedback). And I decided it's not worth the $600 or so upgrading to that. But regarding other brands of solvers, the only I know a bit about is GTO Wizard. I'm fine w/ a subscription payment model as long as a few years worth of paying comes out to around the price of Pio ($600-800). Oh and I play exclusively cash games.

In you guys' opinion, given above, do you recommend I upgrade to a different solver? If so which one? Thanks!
