The Samsung drives are really good. I have 2 x 970 EVO NVMe SSDs in my NAS as read/write cache. Intel drives are also good, but tend to be really pricey. In the corporate PC space, I've also used Crucial and Toshiba, but they typically don't perform as well as the Samsungs.
If you're looking to get a new system, look for NVMe SSD over SATA SSD. NVMe is wicked fast and has lower latency due to not requiring a disk controller between the storage and the system bus.
