Some info I found on another site that I thought would be valuable here too.

REAR AXLES

10-bolt
PRO High ground clearance/very easy to find/Warn full float kit available.
CON C-clip design/smallest ring & pinion of the bunch/considered weak.

12-bolt
PRO High ground clearance/Larger ring & pinion/carrier bearings than 10-bolt/Warn full float kit available.
CON C-clip design/not as strong as 14-bolt axles/getting harder to find.

14-bolt (Semi Float)
PRO Larger ring & pinion than 12-bolt/6-lug pattern available.
CON Less ground clearance than 10 and 12 bolt/C-clip design/heavy.

14-bolt (Full Float)
PRO Strongest of the bunch and very affordable/very easy to find.
CON Low ground clearance due to massive ring & pinion/need 8-lug rims/very heavy

Good to know. The info was copy and pasted from another source, so correction are certainly possibly needed.
