IF your drums brakes are in good working order, I wouldn't expect a huge stopping power upgrade.

The big advantage for this type of disc upgrade is easy of maintenance and the fact that it comes in a kit. If you need to completely overhaul your drums you might find that upgrading to discs doesn't cost that much more. So if that's the case where your brakes are a bit tired, you will feel a difference. If your drums are solid, maybe not so much. Just managing expectations.

Discs are superior, but whether you will notice a big difference in normal driving with a common 11" rotor and single piston caliper is questionable. Now big brake kits, or situations where brake fade can come into play are a different story and discs are an enormous upgrade.

Yup, this is correct. If your current drum setup already has the power to lock up the tires, adding front discs will not meaningfully change your stopping distances.

There's a possibility they could actually make it worse as they may overpower the tire's grip sooner.

To reduce stopping distance, you need more grip, which means a better tire. That may or may not be possible with the 14" wheels.

If you're doing the conversion to get power assist, that's somewhat of a different story and may be worth it depending on your driving style, but again you shouldn't expect reduced stopping distance. Just an easier pedal.
