What's the difference between the 4.10 and 3.21 axle ratios?

Correction: Your Saharah has the D44 in the rear and the D30 in the front. The same as my 07 X. Including the 4.10 gears.
Teh Dana 30 is a much better axle than the C-Clip Dana 35 (POS), and the Dana 35 did not come in the fron of either the TJ or the JK.

Your right, it didnt, but for a brief time some of the '07s got stuck with a D35 in the rear.

I got lucky and got an 07 Unlimited Sahara with the 4:10 tow package. Now you can get the 4:10 only on the Rubi. (07 was the only year for 4:10 option on Sahara.)
I also have a 6 speed. I cannot imagine driving this thing with less than the 4:10. Coming from the previous TJ, the JK simply needs to wind out more to have any power.
If I had to get a new Wrangler now, I would have to go Rubi to get the factory 4:10. There is no way I could stand any less power.
For other reasons, the Rubi will have better resale if/when you get rid of it.
The only other option in my opinion is: If you plan on a big lift and big wheels, you'll have to regear anyway... to 4.88 or 5.13 in the extreme. Thats changes everything... but you might still want the Dana 44 differentials. The Rubi has D44s both ends. My 07 Sahara is D44 rear and D35 front.
Happy shopping!
