What Are Your Top 3 Played ADCs?

I'm trying to narrow down my champion pool and still can't decide which 3 to main.

Currently, my top picks are:

Kaisa - Versatile, can play AP or AD, bad laning phase, great duelist, mediocre in team fights, shines in teams with a lot of cc

Ashe - Strong early/mid game, decent against tanks, always relevant even if I fall behind

About my 3rd pick, I can't decide. Do I go for something even stronger against tanks, Vayne, Varus, or Kog, or maybe an ADC or mage to synergize better with mage supports? Veigar for example
