| I've read that the 32198 has problems when being stressed.
And the 87407 is said to be more stable.
(Probably due to the extended hub bushing)
Would you say, that one should use the 87407 over the 32198 whenever possible?
Or in other words: Unless you have space restrictions, is the 87407 flat out
the better choice?
I'm basically asking, because I'm unsure what gear I should extend my
stock on to build future models with.
I'm trying to reduce alternative items and only get the better (not necessarily
newer) version now.
Because when I re-started my LEGO "carreer", I didn't really know
what I was doing and bought a lot of old parts, where I later learned, that better
and cheaper alternatives exist.

I think you just answered your own question. 
Cheers ...

You do know that there's a major difference between the two gears? One has
an axle hole, the other just has a pin hole. The pin hole will not be useful
in a gear train or anything, really, other than as decor  (not totally true,
I know, but pretty much!)

| It might work as a clutch, if you use a pin with friction ridges?

| *if the mechanism turns fast enough to generate heat, it will expand and therefore
gain passive traction. Technic is complex!

Erm. Now that you say it... I guess that's quite a difference. Yes. XD
I mostly use the 32198 for driving actuators. The 87407 doesn't make sense
there.
For some reason, I didn't really realize the obvious functional difference
before writing this post.
I just though "Oh, look, it has an outset on the hub to be more stable on
the axis.
Why then do people still use the inferior 32198?"
Little derp on my side.
Forgive me my confusion and thx for pointing it out.

| Although... it can actually make sense. (just looked at the 8143 manual)
The trick is: You simply need ALL the parts. I got now.
