I have some of both types. With decent interchangeable tipped pliers like the older 7" Channelocks 907G I have, the tips firmly locate in slotted grooves. There is no movement.
Within the current 920 series of snap ring pliers they offer now, the 927's are larger at 8" and there is also one smaller 6" size the 926. Those two and including the one I have all come with .038, .047, and .070 sized tips. The one larger size the 10" #929. has .090, .108 and .120 tips.
All made in USA they say.
Can't say I've ever had any problems losing tips from not being organized but one nice thing with Channellock brand is you can always buy the tips separate.
I did pick up the ICON 8pc set last winter for $39.99 (but right now they are at $59.99)to have for larger fixed tips. They are all a long nose type pliers for good reach and have either .070 or .090 tips. Inside and outside selections with straight, 45 and 90 degree options.
There was a earlier thread about them at that time

No matter what you choose most everyone generally agrees to stay away from the really cheap stamped ones.
