I'm Thinking of buying Gigabyte Aorus RGB M.2 NVMe SSD or ADATA 512GB XPG SX8200 PRO PCIe Gen3x4 M.2 SSD and Seagate 3.5" 2TB Barracuda Sata 3.0 7200Rpm 256MB Cache or WD WD 3.5" 1TB Red Sata/1TB Caviar Black/ 1TB Caviar Blue which ones should i buy ?

What do you want it for exactly?
Obviously if this is because you want a fast OS or fast loadup then SSD is preferable.
Personally I would avoid any storage drive with RGB in it...

Before you buy an M2 drive, please make sure your motherboard supports it. M2 drives comes as either Sata or NVME but it's up to the manufacturers to how they configure their boards M2 slot which can support either one or both.
By the way, M2 Sata is the same performance as it's 2.5" Sata twin.
