The New Regulated version of the Myo XP, cunningly called the Myo RXP is even better than the standard XP. As usual it's brighter and has a longer burn time than the standard XP. I have always preferred a regulated headtorch so it's a great development. I had a Princeton Tec Apex but the RXP is better.

I have also used a Hope Vision 4 lately but it would be unfair to compare them. £80 against £250
