A useful starting point
These names identify different formats. Begin with a guide for the one you intend to learn, rather than combining instructions from both. Check hand size, turn flow and how a round finishes in the respective reference.
Try it in practice
Try a short demonstration of each format with your group if you are deciding what to play. Pick the learning process that interests everyone and keep the rules visible while practising.
Take one idea forward
Choose one question to revisit next time. Use the current rules for your format and keep the session comfortable for everyone.
