Advice on pruning apple tree

[Falstaff]

I recently bought an apple tree on M26 rootstock. I'm not sure which way to prune after planting. I've uploaded two pictures with the top options. Would you prune right back to have one crown or keep the height and have two crowns.
Any advice would greatly received.

M26 is great for espalier and cordons if you have a suitable fence. With that in mind I would take out the centre growth at the top and take the one you have your hand on back to the first sideways facing bud. Otherwise it should make ten or twelve feet, so I think I would keep the top part of it either way.
