You cant even compare Toytec to Icon, King, Fox, or Overland Warehouse. Icon's, King's, FOx's and OW's are true coilovers. Some with remote res, some without. They offer great off road performance without sacrificing on road ride and handling.
Toytec's are just Bilstein 5100's with an adjustable collar. If you want Bilstein's, great save your money and buy those. If you want a true coilover that is made to perform and last, spend an extra couple bucks and go with Icon, OW, Fox or King.
I have Icon remote res on the front and love them. I had Fox's on my FJ and loved them a lot as well. People wave about King and OW so I am sure they are great as well.
As far as UCA's it is kinda personal preference just like the coilovers. I run Camburg's and think they are great. I have friends that run the Icon's and love them as well. People wave about Total Chaos UCA's and Light Racing UCA's. The nice thing about Icon UCA's is they have a dust cover on top of the ball joint so you dont get dirt and dust inside there. They are quieter for this reason. The Light Racing UCA's utilize the stock ball joint so they are very quiet, but do not provide as much articulation as the other UCA's out there.
Hope this helps. Not trying to knock Toytec but they really are not even in the same realm as the other Coilovers. That is why they sell Icon, so people that really want a true coilover can buy those instead of theirs.
