I agree that this is a great price. As for your present PV and the clone Vivi Nova always buy Vision (brand) Vivi Nova.
Vision Spinner Tank Combo
I believe your present PV is a smok Tek 3.7 volts PV- 1.7- 2.0 ohms for a warm vape. 2.4 ohms for a cool vape. 2.8 ohms is far too high. Best ohms for the Spinner is either 1.8 or 2.4- 2.4 is good cuz it's allows you to use the higher voltage on the Spinner. I own both Twists and Spinners and prefer the Spinners cuz the dial is much easier to turn and the voltage markings are easy to read.
Just some info but the head on the left is a clone while the one on the right is a Vision brand. Also, in regards to the ohms of the head, if you look closely should be able to see the ohms # stamped on the head- 1.8, 2.4 and 2.8 ohms.

OMGumballs!! Thanky!! Thanky!! I'm a show me type, so your pictures are incredible. Plus, I'm glad you answered those questions. I didn't know what the difference was between Vision vs Smoktech and you gave me additional knowledge regarding the spinner/twist. There really is a huge difference in reading the voltage setting on the spinner. Looking at all the vendors, they both looked exactly the same to me. I did notice the visions vivi tanks are all out of stock where as the smoktech was not, which kinda gave me a clue that vision was of a better quality. lol Also, thanks for the info on the ohms. I noticed when purchasing replacement heads, you are given 3 choices, and of course, I sat staring at my computer screen, totally dumb founded as to which one I was suppose to get. LMAO!!
