+500bhp dragster bikes use master-link with clip with no issues. Power-level doesn't matter because it's applied 90-degrees to chain-pins and there's minimal force against the clip. It's vibration-levels over time that walks it off.

And most people who have had problem installed clip incorrectly. These people would have same issue with staking a rivet link in place as well. So one would not be better than other.

Issue is that there FOUR different ways to install master-link clip. Most people know about 2 of these cases and install opening of clip facing back. However, there's also beveled vs. flat edges of clip. This is created by the stamping process, similar to washers where one edge is sharp while other has slight curve. It may seem intuitive at 1st to install with flat-edge against chain plate so it sits flush right? NOPE, this places beveled curved edge outwards where it can slide off groove in pin easier. Proper installation places beveled side INWARDs, towards chain plate. This makes it more difficult for clip to slide out of groove.

This picture shows incorrect installation of clip with curve beveled edge of clip on outside. You can see this smooth beveled edge on outside edge & tip of clip as well as on inside holes that goes over pins.

These picture shows correct installation with sharp edge on outside and smoother curved edge on inside. You can sometimes spot the sharp side by it showing some post-stamping machining to remove the burr on opposite of smooth edge. In this case, you can see shadow between clip and plate shows curved edge facing inwards.

This last photo shows some rounded edge on bottom of inner hole of clip. That's from pliers being used to remove previously. That's OK, because actual hole that engages pin groove is still sharp on outer edge. This one can also use a little deeper seating of clip into grooves (see gap at seam where open-ends meet). The safety-wire is good extra insurance. Not allowed in some racing circles due to it being stop-gap measure since properly installed clip won't need safety-wire.
