Just to clarify, I would say a trackbar on the front of the axle is standard given the requirement for having a mechanical link to steering. Since there is a trackbar then a single or double upper link can do the same job, since they are not triangulated. So we do need to be somewhat precise in our language, triangulated 4-link V. 4-link. All stock wranglers have front and rear 4-links so if anything is standard then 4-links are standard since that is the OEM config.
I think in custom application the midarm front 3 link is going to be easier to integrate than a midarm front 4-link with trackbar because its less links and getting the desired separation with the exhaust on teh passenger side might be a struggle though that is conjecture as i haven't tried it myself.
I have many pictures of the midarm installation in my build thread.
