I have found the Motive Power Fill to be worthwhile. I have used it for several MTF, ATF, and diff oil changes on several cars, primarily BMW's. And it's made in the US, which was a nice bonus.
After dealing with leaking or messy fluid and transfer pumps, it's been nice.

This is what I use, and I have been using the same spout for the last 25 years
The spout screws on to litre/quart bottles and squeezing in two litres of gear oil takes all of ten minutes. No need to even wipe down the spout when handling different oils like gear oil, engine oil, ATF, PSF. I don't use it for brake fluid since the least amount of oil contamination can cause problems.
It is not practical to use this on heavy truck diffys which take 16 litres or so. There I pump it directly with a pail pump through the diffy fill hole from the 5 gal pail the oil comes in.
You're not aware of all geometries/scenarios, and that's fine, but some things have very limited access.
My diff for example has very limited access that a bottle like that wouldn't fit.
The MT fill hole has enough space for an 8mm male hex socket on a torque wrench with a fat head, with a cm to spare. Not going to fit a bottle like that.
Lower unit full pumps work decently for shallow containers. Not sure they will last any better though...
