Adrianvr their scenes are just very very life like, not necessarily their older 7k or 5k scenes. But the 8k scene are really "in the room".
They don't feel over cooked either with contrast, saturation, etc. A lot of the slro or spy seem overly processed in that department. Also, euro gals over at czechvr, so they're usually fit vs chubby or out of shape, usually. Now the stuff I find on slro is usually more hardcore, hence why I've had my slr sub for 5-6 years.
I also kinda like how CZvr is a more... idk how to describe it... slower scene? Ie: when its BJ tine you can settle in for 10min of BJ, when its rev CG settle in for 10min. Slro and spy seem to be quick cut scenes lately. 30s of bj, 45s titty fuck, 90s CG, back to 120sec of bj again.
