Favorite gear ratio for street car

I’ve only owned the car two months and put 25 miles on it. Highway use is low maybe 15% of total driving, but longest highway trip would be about 30 miles. With 4.10s it did good but I the car started with a lot of problems... been chasing the non mechanic repairs out if it. So far I could have started with a better car for what I am spending to save this one. I just installed new Espo 6 leaf +2 springs since the old ones were wrapped badly from not me. So as far as hooking up im good with a nice feeling launch, if that makes sense... i ran the math and 4.10s at 65 is 3300 rpm, 3.91 is 3100 rpm, snd 3.73 is 2900 rpm, not big changes but whatever. I like how the lower gear ratios feel, just wondered if going to 3.91 was smart... not a racecar, but want it to feel like it can run high 11 or low 12 quarter mile, but nice street car manners.
