Imo the best is Bombay Sapphire!
PL vodka best
Bombay or Tanquerey. Hendrick's is alright too.
E: Aside from a slice of lemon, try squeezing some juice in from the lemon as well. Acidity balances out the bitterness nicely IMO.
Bombay is good but a bit boring. Try Hendrick's or Tanqueray.
Hendricks, not even close :)
Bombay is good. perfect for gin tonic.
In the cheap range, Tanqueray is definately the go to gin. Are you willing to pay a bit more then the Tanqueray 10 is a good upgrade. Hendricks and Monkey 47 are very nice as well.
Also for a very nice gin drink try:
1 part gin
1 part whisky (some tullamore dew/jamison-ish)
1 part lime syrup/sour mix
2 drops of bitter (angostura is my go to)
1 slice of lime
Pour into a glass with ice and top it off with ginger ale. Freaking delicious!
