The ranger 8.8 and 7.5 both share the exact same axle shafts so there isn't any strength gain there.
The carrier and gears are a tad stronger tho in the 8.8
With 31" tires and a 2.9 either rear end will be just fine.

The 8.8 is always the better one if you need to change but if there is nothing wrong with what you have and are happy with, I sure would just stay with it.

The one thing about an 8.8" is that if you need to work on it the
8.8" is much easier to perform basic maintainance tasks on, particularly if you need to pull an axle shaft, rebuild a limited slip etc...
An advantage of a '93-up axle over ANY '83-92 axle is that it is 2" WIDER
thus offering more stability when offroading.

That article is about swapping in a 31spl exploder 8.8, which is different from the 28spl ranger 8.8 the OP has. The ranger 8.8 is a bolt "up" swap, whereas the exploder axle swap requires relocating the leaf spring perches, shock mounts etc.

- If you're not making mistakes, you're not learning.
Unless you're switching up gear ratios, adding a locker, or fancy Limited Slip, just keep the 7.5".
Although, if you open up the cover on the 8.8 and verify what gear ratio it has in it - as well as whats in your truck now, and if it's a L/S unit or not, then it's a no brainer. Better center section, and likely 10" brakes as well, with no drawbacks. Like you said, it's a bolt in swap.

There are two diferences on an 8.8 over an '88 7.5"
First is that like ANY 1990-up axle it has the larger diameter pinion flange
Second is that '89-up rear axles use larger diameter lower shock bolts
The hole in the bracket is larger as is the sleeve in the lower shock bushing.
Neither problem is especially difficult to deal with.
