Anyone else experienced this? Virtus 1.0 AT vs Slavia 1.0 AT

Despite technically being identical, I felt a noticeable difference driving the Virtus and Slavia in 1.0 AT configs. I test drove them both (twice) and both times the virtus seemed noticeably jerky, while the Slavia felt much smoother. The difference was noticeably large and other members alongside me noticed the same.

Anyone else experienced this? What could be the reason behind this? I'm confused because they're identical mechanically so shouldn't their driving experience be the same?

I like the Virtus more but this driving difference has made me more inclined towards Slavia. I can't go for 1.5 DSG due to budget (1.5 DSG is awesome though).
