It all depends how you, personally, define 'best'.
Nowdays you can easily get dinotte levels of brightness from a P7 torch combined with a red LED torch.
You don't sacrifice any reliability or runtime either.
My 2 x P7 torch outruns most dedicated cycle lights and puts out a lot of lumens.
So, if VFM is any part of your definition of 'best' you'll find a lot of happy P7 users.
