Cane pruning has worked on everything for me. That's on about 40 varieties of mostly seedless table grapes both hardy and non hardy. Spur will work for most but is used to some large degree because it's cheaper and easier.

If in doubt cane prune. I spur prune my 'Crimson Seedless' because I like the look of it in the garden and I can do it quickly.

Thanks for the advice. Does came pruning increase your yields??

Cane pruning increases the yield of some varieties that don't have fruitful buds when spur pruned. When last yrs canes are cut back to 3-4 buds for spur pruning of certain varieties, those buds don't produce fruit. Those are the varieties that should be cane pruned. For many cultivars either method works. Yield can be easily adjusted with cane pruning based on how many buds are left and how many clusters are removed. Getting yield isn't the issue. The issue is how many clusters can one leave without reducing quality, sweetness, too much.

I'm a backyard grower, so aesthetics are as important as yields. And since I'm thinning out and removing some clusters, what value would there be in having more fruit to thin? Here's my vine leafing out from May:
