When I was first starting out, I stuck a LOT of cases. Now, not so much. But it still happens.
The RCBS tool works every time for me. There is some chance you will damage the decapping rod or expander button in the die. I always keep spares of these more fragile items.
Sucks to be down until you can get a replacement.
For a bottleneck case, I unscrew the decapping rod from the die. The expander ball will stick in the neck of the case. Just pull hard to jamb it tight so you can unthread the rod and pull it free. This will leave the expander ball and decapping pin in the case. After you get the bad case out, you can dremel or hacksaw it open to remove the ball and pin.
For a straight walled case, back the decapping rod out as far as you can.
Be very careful when you are drilling and tapping out the primer pocket. Let the drill do the work and don't apply a lot of downward force. You want to stop as soon as you break through the web. The best way is to start with smaller bits and work your way up to the 1/4" bit.
If you watch the RCBS video, you will see that their bolt is sticking up 3/4" when they have the threads started. This is not good. When you screw down the bolt, that 3/4" must penetrate the case before you get any pull on the stuck case. It may be damaging your decapping parts. Replace the provided 1/4x20 allen head screw with a shorter 7/16 hex head bolt.
Replacing the bolt buys you two things:
1)You only need the bolt to be long enough to fully engage the threads when it bottoms out. Anything more than this risks damaging the decapping parts.
2)The 7/16 hex head allows you to use an adjustable wrench or long box end to apply more torque to the bolt. Less effort and less chance of busting a knuckle. The stubby allen wrench kind of sucks.
Even less effort if you put a SMALL dab of grease on the bolt before you start threading it in. A dab of grease where the head meets the hole in the cup too. You want all your torque to be applied to the extraction rather than lost to friction in the tool. It is amazing how much easier this makes the process.
I clean everything up afterward using spray brake cleaner. You need to make sure there are no brass chips or grease in the die.
If the 1/4x20 bolt pulls out (this is rare), you can tap the hole for a 5/16 (8mm) bolt or even bigger. Then use a socket or washers instead of the cup that comes in the kit.
I could have extracted 20 cases in the time it took to write this. Its pretty simple.
