I used a vertex in my 15 xc300 when I did the top end, I had 100 hrs on it & was still running great. Measure your base gasket in a few spots,Ktm uses different base gasket thicknesses to achieve the proper measurements for piston to head clearance, What Ktm Calls " X" distance. If your happy with the way the bike runs, put Oem parts back in. Slavens racing makes wrist pin clips that are much easier to install compared to the stock vertex clips, the vertex clips are thick & tricky to install compared to most clips. I have no problems with wiseco Pistons, have used them in many of my bikes, but when I see a piston that has 100 hrs on it that was still within specs, I"m thinking its a good product.
