Hello,
I don't have WB10 running anymore. From what I remembered, performance and its visual wise it is similar. I believe, WB11 might be more compatible with Windows 10 current version. If you're not updating your Windows 10. WB10 should still work normally. And you still using Start10. If you moved to Start11, I don't think WB10 support Start11 Win10 and Win11 skin panel capabilities.
Thanks
