The rubicon make sense if you are planning to lift , get on 35's and run moderately difficult trails. Otherwise 90% of the reason you bought a rubicon will end up getting replaced when you get into more technical or difficult wheeling.
The 44 is just the differential upgrade, the gears arent significantly deeper than a tow package sahara, the t-case is the only thing that you would probably keep for the long haul
If you are just getting into jeeping then it makes sense to get a sahara or special package. You will save some money on the original purchase, 90% of the jeeps I see will never do anything hard enough to require an upgraded axle much over the standard sleeve, gusset, truss that you will do on the rubicon axle anyway. If you go to 35" or bigger tires on a rubicon or sahara a regear will benefit you, If you plan to get into really difficult wheeling the stock lockers are known to fail and a lot of rubicon guys go to the aftermarket lockers for added strength anyway.
In the long run, Its your life your money your jeep. Research the parts you want to have on your jeep more than the package then get the cheapest package that fits your want.
I got a "sticker package" MOAB Unlimited Edition because i knew i was going to go to an aftermarket housing up front regardless of stock front axle, I opted out of the rear locker in favor of adding an aftermarket locker, i also opted out of the the tow package and got 3.21 gears knowing i would be re gearing. Now one year after purchase I have a Core44 front, 5.13 gears and front and rear lockers and im still 8k cheaper than what i could have gotten a comparably equipped rubicon unlimited for assuming i could have gotten the same discount on a rubicon as MOAB
