Help me figure it out before buying

Hello, what is the difference between TinyFab UP! / Cetus CPU V5 (USB) and TinyFab UP! / Cetus CPU ESP32 (beta), ?? I want to upgrade one that matches the mini-1 and if you like it, transfer them all to your processors. And the second thing. Would you like to lay out the complete instructions on translation, after replacement, by connecting to a common slayer, for example, CURA. and then such a replacement without additional information scares. Will they work with the standard UP mini kit? What else can I order from your website right away that will improve the performance of my printer? maybe a bed with a higher temperature or something else?
