What is your end game with the car. What tire size. I'd first recommend going online, look at some of the speed, rpm, gear , tire calculations. And see what your choices may give you rpm wise and speed wise. I have a 98 convertible with auto. Engine only revs to 5200ish stock. So your rpm limit needs to be taken into consideration also . I would determine your rpm at your desired speed with O/D button off . Then consider gear choice
Really no universal correct answer. Gears don't manufacture power they just change the dynamics of when it's applied.
After 1st gear they can't exactly increase torque to the wheels (because you could always just downshift for that) but they do change when and how often you shift which will be of different benefit in different situations depending what you actually expect from the car.
On my 94 GT even if it was free & someone else was doing the work I'd keep the 3.08 gears it came with because I already like how it drives. I'm not racing I'm road tripping.
On my wife's 2002 I went to 3.55 gears from 3.27 stock, on my 96 V6 I'm putting 3.45 gears in from 2.73 stock. These are travelers/street/daily cars and going deeper would only mean shifting more often and making a little more noise on the highway.
My point is to consider what you actually want from the car - the answer as it pertains to gearing may surprise you.
