Machine torch if you’re going to just use it for the Crossfire. Sometimes you’ll be able to get a package with a machine & hand torch for not a lot more than with just one torch. You can then use it for hand cutting too.
If you can only afford one and you are also going to use it for hand cutting then you need to buy the hand torch and use it for both - it’s not quite as clean an install on the table as the machine torch - you have to make sure it’s square to the table, you’ll need to remove it (& then need to re-square) when you need to replace consumables and you need to be careful not to deform the shield or nozzle when you tighten it into the torch holder.
You can’t use the machine torch by hand.
