Moog units are fine. They`re stock replacement,stiff and cheap but fine. Afco has similar units that are cheap and looser out of the box but offer no other advantages.
Howe Precision Series ball joints are a whole different animal. In stock heights you get no change in geometry but their CNC machined heat treated steel construction is much stronger (not that the Moogs aren`t strong enough already) and much smoother (like a true bearing). They`re made to easily outlast EO style ball joints with O ring sealed housings,baked on low friction coating etc. They`re also easily adjustable for tension and wear without taking them out of the car. All that is nice and for many people well worth the price of admission. If you`re running something like the excellent AFX tall aluminum spindles already this is the only area where the Howe ball joints etc. are superior.
Where they blow everything else in the catagory away is the fact that they`re modular and can be configured to make serious geometry changes with
stock spindles. On cars with really lousy stock geometry like early Camaros that`s a HUGE advantage. Bolting in the proper ball joints can in one configuration make a larger improvement in the geometry than doing the old G Mod (but be totally bolt on) or (in another configuration) can be combined with it for even greater gains. A taller tie rod end configuration can also fix about 80% of the factory bumpsteer. I guess you could call those, some other advantages....

Of course there`s no free lunch, when you make actual profound changes in one place you need to make other changes to keep systems working in harmony. In this case different length tie rod adj. sleeves and upper A arms are required but the net result is totally revised and improved geometry and much better drivability and performance....or you can just have new stock ball joints.
Do what you`ve always done and you`ll get what you always got.
