Bicycle is always the way to go imo for cheap cards
They look nice, they're super cheap (if you're in the U.S. Costco sells 12 for $20, but a regular 2 pack is just $5. They're cheap), they hold up well, and you won't be terrified of damaging them.
Isometrics are more meant for cardistry, as the others have said, stick with standard backs (Bikes, Tally-Hos, Bees, et cetera), no reason to buy custom cards unless performing.
For cardistry, it is 100% virtuosos. They're really cheap for what you're getting. You can find them on eBay for under $20 and they'll last you over 2 years. I've had a virtuoso deck for nearing 3 years now and they feel brand new! I suggest the FW17s because they have a preferred stock but if you like thicker cards, try to find the SS16s.
