GKTech - They fit well, GK includes different length ends for the heims to accommodate different length inner tie rods. They do what they need to, I haven't had any issue with them. I do not like that the heim joints are very large, even more so with the dust boots, mine actually hit the lower control arm at full lock. The finish is subpar, the heims came out of the box with the paint chipped in a few spots.
SPL - Fit is perfect, included hardware is very high quality. Only include one length end for the heims, will need longer inners to run these on a car with extended LCA's/angle mods. Heim joints are small and a proper sealed part, no dust boots required. Overall finish is top notch.
If I was buying another set for any of my cars, I'd go SPL without hesitation over anything else.
