Have you looked into JBA Offroad? They make UCAs for the 4th/5th gens. Their current model seems to have positive reviews and guys are getting 3+ on caster. You can service/swap out the balljoint without taking off the control arm. Their customer service is great too. Their first run of UCAs in early 2015 did have problems with Tacomas but it was addressed quickly by the owner of JBA.

I wanted balljoint UCAs so I was on the fence between JBA, SPC, or Camburg. I've read Camburg's CS being pretty non-existent. Their BJ UCA's net barely any positive caster over OEM, and you will need to remove the UCA to press in new balljoints.
LR/SPC UCAs are made in China and have spotty reviews on various forums. Some have had horrid experiences with them while others have nothing but raving reviews. It's a toss.
I think the SPC UCA's I received a few weeks ago said "Made in Spain". Maybe it was another part, I don't know, I've received about 40 different parts the past few weeks.
SPC's seem alright to me but I've been using OEM UCA's on Tacomas, Tundras, no experience with aftermarket.
I did research and saw SPC had problems until 2016 when they updated the bushings and washers, added a grease zerk. Well, they're on the truck now so hopefully I installed them correctly and we'll see how it works out.
