Hey there. I bought Rocksmith 2014 for PS4 and played it for a few days. I'd say it was a less satisfying experience than the PC version, which I have now bought. There's was some noticeable latency on the PS4 but I'm confident I didn't have it set up the best way, however. Having now moved to the PC version, I'd say that the extra flexibility (content and updates) that you get and no noticeable latency (depending on the specs of your machine of course) mean that the PC version is a better bet despite the fact you have a PS4. My advice would be to use the PS4 for straight gaming and stick with the PC version for Rocksmith because any potential extra costs (as you suggest in Russia) of purchase will be outweighed by the extra benefits. Also consider that running it on a laptop means you're ultimately portable and don't need to tie up the use of a TV in the house. Hope that helps
