Re: chuck recommendations with apologies

I do not know if you have spent your money yet, but I do have an opinion based on quite a few years of turning and teaching. Now, some may laugh at the "quite a few years" part, but it is a lot for me, and I have learned a lot in the process.
Both chucks you mention are the same size. A chuck is not a necessity, it is a convenience. So, if you want to be convenient, you should go for as much luxury as possible. I teach students how to hold a bowl or hollow form using a faceplate and a waste block if that is their budget, or a chuck if they have the money. While both the chucks you mention will work well as far as holding, there is a difference in the convenience factor.
The Talon wins hands down as far as I am concerned for several reasons. First, it is keyed, and it turns the way most of us are used to - righty tighty, lefty loosey. The Supernova also uses a key, but it turns in the opposite direction. The Talon uses a straight tenon. The Supernova uses a dovetailed tenon. Both use a dovetailed recess. In my experience it is easier and faster to turn a straight tenon. It is also easier and faster to retrue it on a dried and warped bowl. The Talon has a better grip with its serrated jaws. Since every single piece I turn either has the tenon removed or returned, any marks from the jaws are a moot point.
I personally do not care for a recessed dovetail. It is too easy to break the wood, and I know that from experience. There is no one I know of who is strong enough to crush a tenon beyond usability. Even on a large bowl, the size of the tenon is an insignificant amount of wood. For a plate of 3/4" thickness, for example, a tenon of 3/32" is plenty, and even it can be turned into a foot. For larger bowls up to 6" or 7" deep. a tenon of 1/4" to 3/8" is plenty of wood to hold.
There are a lot of things you can do with a chuck besides hold bowls and vessels. I will not go into it all here, but suffice to say, the longer you have it, the more uses you will find for it. Again, it is not a necessity, but a convenience, and if your time in the shop is limited, it will be worth anything you spend on it to make that time more productive and enjoyable.
