PD 10 vs PD 9

[Todivefor]

I am running and wanted to use Parallels 9 to test Yesemite before updating. Failing to be able to do this, I went ahead and installed Yesemite. PD 9 is working fine to run my W7, Linux, and W-XP. Is there any advantage to upgrading to PD10? Does it run faster or have something to warrant the $49?

Hadn't seen this: https://forum.parallels.com/threads/how-to-downgrade-from-pd-10-to-pd-9.314338/. Guess it answers my question. Came from VMware 4-5 years, have paid for several upgrades. May be time to re-evaluate Fusion.
