I run the WKOR sliders and the GIS DIY skid plate with trans pan.
Both are hell-for-stout.
Can you post some photos of your t-case and trans skids?
I'm just looking at pictures online and shopping for a skid myself, of all the options listed here I think I like the GIS skid plate with trans pan the best, because it uses connecting brackets to the frame both on the back side of the t-case skid and on the front side of the trans skid to prevent excessive torque on the primary crossmember and its mounting bolts. Most of the other options have long unsupported overhangs (especially the trail tailor creeper). I haven't run any of the options myself so I can't speak to real-world performance.
