What type of transmission fluid do you use?

Sorry to resurrect an old post. But given the issues these RX300s have with the tranny I would like to know a bit more about what others on this site have successfully used. I am not opposed to using Genuine Toyota T-IV. I have looked over a bunch of older posts and still have not concluded what is best.
Is there a consensus on which ATF we should be using? Should I be sticking to the Toyota T-IV or Do you recommend Castrol, Max Life, Mobil or others?
Or, doesn't matter as long as you change it frequently?

The way I look at it is Toyota designed the car and the fluids to be used in it, so I stick with their recommendations. I've changed my fluid & filter twice and used T-IV both times.

This may sound a little strange, but here goes; When I had my 2001 RX300 I noticed that when I used the Toyota brand fluid, I had too much slip-n-slide from first to second gear. When I used the Castrol multi Import vehicle fluid, it shifted MUCH better. However, on my now RX330 this trans works the best on the Toyota brand fluid. Why? I have no idea.
As Lexus114 notes, I do notice a little bit of hesitation from 1st to 2nd gear when I ease into an acceleration. My transmission has about 80K on it. The current fluid is red and smells just fine. I would like to avoid premature failure.
Being so new to this vehicle, I was hoping to gain some anecdotal insight from others who have similar results as "Lexus114" using a different fluid like the "Castrol Multi Import" to improve the transaxle performance?
