Razer Huntsman V2 Questions..

The Razer Huntsman v2 has good reviews and im thinking of buying it but I have some questions. I know there is RGB lighting under the keys but is there lighting under the keyboard? Are the linear keys really that different from the clicky keys and if they are, does it take a while to adjust to, or is it just weird for a little bit? And some questions that aren't related to the Huntsman. Basilisk V3 (wired https://9apps.ooo/) vs Deathadder V2 for gaming. And finally, Is the Basilisk V3 pro (Wireless) faster and better than the wired version? Because I have always thought wired means faster and better. Thank you, if you have read this and answered some of my questions.
