A front locker is how you can get yourself to places you shouldn’t be. Plus I think the SR5 rides smoother with no shimmy.

I have experience with using ATRAC extensively, with having an ARB air locker and now with a Toyota E-Locker, the main reason I purchased the TRD ORP model.
I had my 2005 SR5 for 239,000 miles across 13 years, about 1/4 of those without the ARB locker. I pushed ATRAC as much as possible and admire the capability it brings. The big disadvantage of ATRAC is it requires those wheels to be spinning so the wheel sensors can get a good reading. That is not a good thing for low speed crawling especially when there is no wheel spin for ATRAC brake pulsing to keep the diff "locked" up. That means you mostly have an open diff until a wheel happens to spin.
Because I take my off road trailer so many places I finally felt that the limits of ATRAC called for a rear locker to be installed. It is a long story but one critical point is proper installation! I was dismayed to find out how poor a job a local Jeep shop performed, especially at not properly installing the copper air line. It is important to note that ARB builds a quality product but a bad install negates that. It was due to the patience and support of ARB America that I was able to get things right. However, I got really tired of all of the down time and removing and re-installing the 3rd member on my own. I became almost too good at installs and learned a lot about air lockers. Be sure to be either a good mechanic or carefully choose the shop that installs your ARB.
Once the ARB is working properly they have a strange habit of "burping" diff oil back up the air line where it dribbles out and makes a mess. A small concern is the rubber seals in the ARB so be sure to keep your diff oil clean and changed without fail. Also keep in mind the air locker requires an on-board air compressor so instead of the smallest ARB compressor just budget for the bigger CKMA-12 so that you can also air up your tires.
A Toyota E-Locker has the advantages of no air compressor, no air lines and no air seals to worry about. It is an OEM part and should be covered under the drive train warranty. (I'd better go read the fine print though!) You can get parts at all Toyota dealers across the nation. There are "hacks" to allow bypassing all of the interlocks so that it can be engaged even in 2WD. I have read of complaints of slow engagement but I have not experienced that issue yet. It seems that if the e-locker is used often enough it will always engage and disengage smoothly. I guess if you are a hard-core rock crawler you'd want to be sure to protect the e-locker's solenoid from getting bashed.
The actual problem with the hood scoop bling is blocking some of your view of the trail close to the front of the 4Runner.
In closing, you need to either have no worry about the extra cost of the TRD ORP or understand thoroughly if any sort of locker is needed for your style of off-roading. Then budget accordingly.
