Surely that would depend on what you are intending to make
The Shark jaws. They do almost everything for me.
I dont have Vicmarc , but I agree with the two comments here. I have several SN2 Nova chucks and three of them have the equivalent of the Vicmarc shark jaws. Why three I often have several on the go at once and the shark jaws will do most everything for me as Gabriel mentioned, of course what you are turning will influence chuck jaws choice. But the shark type is very near to a universal jaw bowls or hollow vessels and if you have only one chuck its probably the best option to start with.
what are the shark equivalent jaws for nova. Cant seem to find any
There aren’t any. I did find these and am considering trying them out. Need to either buy their screws or a 10.5mm drill for the screw holes.
Thanks for the link! I ordered a set. Won't get here till the 17th or 18th though. Will post how they are when I get them.
I use these

Just curious what you all are trying to hold that a normal tenon won’t work?
Nothing. I prefer, and use, the jaws below, #2 Stronghold Tower jaws. Provide more room around the bottom, capable for bowls or long spigots for vases, hf’s, etc. I happened to see the jaws linked to above and posted for the OP. They are bery similar to Vicmarc shark jaws and fit Nova chucks.
Doug none of my Oneway jaws fit any of my Nova chucks. Although I have some of these types of jaws for different brands of chucks I never use them. A dovetail tenon has worked for me for 25 years.

I believe what he means is that (his pictured Stronghold #2 Tower) is a version of jaws that fit Nova chucks, since Charlie Hampton was asking about equivalent of Shark Jaws to fit Nova (which there aren't any Shark Jaws for Nova)
(and BTW Thanks, Doug. I've added a set of those to my want-list) I also use tenons for the vast majority , but some projects which I want to put on the lathe are not always conducive to cutting a tenon or recess , and those rare times I wasted hours of various attempts to jury-rig a holding method for my project could have been saved by having a Oneway chuck with shark jaws....
No I do not mean the stronghold jaws fit Nova chucks. I said I prefer and use those jaws (which have a 1/4” deep dovetail at the top).
The jaws I linked to are similar to Vicmarc shark jaws and do fit Nova chucks. Those shark jaws allow some of the same benefits as the Oneway tower jaws - taller for better bottom access, with a dovetail at the top. They do not have Oneway’s profiled patented design, which IMO beats all other designs, allowing excellent retention at any opening size.

I use the standard jaws that come with my chuck. If I am turning spindles, I will turn an appropriate tenon on each end. I did try some stepped jaws, and they just don't do much for me, other than gather dust. Those tower type jaws, if I was to use them would be more for turning spindles. I do start my spindles between centers first, then turn the tenons.

I have a 50mm and 100mm set that I got for free when I bought a couple of Record Power chucks. I tried the 50mm today for turning a tree. I was impressed. I had 2” round by 14” long piece and when it got too small I had to take the tail stock away. It was very solid without the tail stock.
It's interesting that vicmarc sells the shark jaws is 48, 55, 74, and 88 mm. ( For the vm100 ). But they just sell a 50 and a 100 for the dovetails. This implies some nuance is choosing the right size. Or maybe not.
Hmm, I'm not 100% sure that is right, although maybe in your part of the world they don't stock or sell it.
They have a 144mm external, 128mm internal., set of dovetail jaws for the VM100 chucks. This is a very handy size for wide bases on platters, and the like.

Dovetail Jaws VM90/100 | Vicmarc
Dovetail Jaws have been designed to mount bowls by expanding into a recess or clamping onto a spigot. The sizes indicated on the drawing are when the jaws form a perfect circle. VM90 and VM100 chucks provide approx. 38mm of expansion beyond these specified sizes. All Dovetail Jaws have an...

Edit: they also have the 70mm two stepped dovetail jaws, which I have and use a real lot. Part number V00644.
Right, good point I was simply going with what Packard woodwork sells. There may be all manner of vm items made that pw doesn't sell.
