What viscosity is called for? 75w90?
If the spec is 75w90, I would look at something like Motul Gear 300. It's dual-rated GL4/GL5 and has a very stout basestock. I have used it in several cars and it has held up to track use and hard driving.

I've been using this when I've serviced a neighbor's Subaru. A bit cheaper than M1 or Red Line, but I doubt most diffs will complain. I think most of the Lexus RWD/rear wheel-biased AWD systems use either open or Torsen diffs.
Red Line 75W-90 also works fine in these.

Even though I mentioned Motul Gear 300 up top, I would tend to agree assuming the car isn't going to the track or running some crazy power over stock.

Its a rare Lexus 6 speed manual and its time to replace the fluid.
Nothing track-wise, its a DD
I keep hearing some good things about Amsoil in the Lexus IS community and of course RL, too.
There is nothing shared, it is a manual transmission only. Toyota's change to GL-5 from GL-4 coincided with a change in the material used to manufacture the synchros (not sure the exact change). I've used Redline and Amsoil in a few RA62's, as well as some generic 75W90 GL-5, but I've yet to find anything that shifted better than the Toyota Gear Oil Super 75W90 GL-5 08885-02106. It's a factory-fill fluid that comes in a can from Japan:
I know nothing specific about its additives or specifications beyond the fact that it doesn't seem like anything special at all, just an expensive mineral oil that seems to work very well.
Your mileage may vary.

I say it's time to place an order from Japan
Nothing worse than a [censored] shifting manual tranny.

It can actually usually be ordered from a local dealer, as it is in the North American supply network.

Just double checked and it actually looks like the updates were done to the countershaft and not the synchros in 05/2006. Interesting.

Royal Purple Synchromax 75w90 is dual rated for GL-4 and GL-5 and would seem to be a good fit for your "transitional" application. (By that I mean a tranny that was originally spec'd for GL-4 but with updated materials that call for a GL-5).
I have used redline 75w90NS, Motul Gear 300, walmart supertech 75w90 syn blend, subaru super S
and a few others in subaru MT that spec gl-5.
Motul was the best shifting, and had good shift feel for the longest.
Redline was good and widely available.
The supertech was surprisingly good for 4.xx/qt
