I had a 1994 sr before my trooper and liked it quite a bit. A few observations I had:
It says to run 91 oct gas but mine ran fine on 87. I experimented on some long 1000 mile pluse trips and found that if I ran 91 oct my hwy mpg was considbly higher. It went from 16-17 hwy to 19-20 mpg. From here to Moab it made quite a difference.
Another thing, you mentioned the big sunroof. If the power switch ever fails (which is kind of common) there is a special tool in the toolkit in the door that will allow you to hand crank it open or closed.
Also while the third row seats don't come out without tools like the fj80, they don't take much to take out. Each seat has three (I think) bolts to remove the third row seats, which gives you a lot more room in the cargo area.
Overall I loved my SR and only sold it because it had 230,000 miles and I wanted something different. I sold it t wo years ago and still see the high school kid who bought it driving around all the time.
