Opinion regarding BlackWidow Tournament Edition Chroma v1 & Kraken

I'm planning to buy my first mechanical keyboard. I had deathstalker which eventually stopped working after years of use. Can someone please suggest if its a good idea to buy Blackwidow TE Chroma v1, does it support synapse 3 software? I've deathadder elite and it works with synapse 3 so want to keep it on the same version.

and if someone owns a pair of Razer Kraken Pro V2 please give a review.

thank you.
