Just so you know, the word 'best' in this context is irrelevant. What's 'best' for me probably won't be best for you, and further, there's no universal 'best' way. It depends on the situation.
A reveal I've been having fun playing with lately is the one Ricky Jay calls the "South American" way - where you do a one-handed shuffle, but leave the cards interwoven and let them cascade into your other hand, leaving the selected card sideways in the hand. It looks very pretty and I enjoy it.
