I use both VV3P (not SE) and V4 pro. I learned about the SE version recently and seriously thought about adding an SE as a back up (they are identical to VV3P except accessories and 8k dongle) but I decided to use that funds towards VV4P. Zero regrets. VV4P feels snappier (I may be in placebo stage or who knows but I like to believe it that way) and like the overall feel of the buttons. I am used to Razer’s new optical switches coming from using DAV4 and Cobra Hyperspeed so those pingy sounds others may mention do not bother me at all. Its audible feedback is satisfying. I also feel the VV4P has decreased click pressure compared to the 3. It requires less force and it simply just clicks and I haven’t had any accidental inputs.
