The best performing card is the Sandisk Extreme Pro, but the Kingston and Sony cards also very fast and can sometimes be found at a less expensive price. In real world shooting conditions you probably won’t feel the difference of 5-10 MB/s with casual shooting, so it might not be a bad idea to go with a less expensive option.
However, the buffer on the T6s is not very big and if you want to do a lot of burst shooting you could run into a lot of wait time while your buffer clears.
