In my book, it is like asking, "should I get a Merc, BMW or Audi?"
It is down to personal choice! I have all of the bats on your list and all are excellent!
The Affiniti I have (got it a couple of years ago) is superb but I cannot vouch for the newest ones as I have no idea where they are made currently?
But L&W have always been superb....hit my first 50 with a L&W and the Sig I have is a classy bat that is excellent in every way (pick-up, feel, response, profile, etc)
But I have also had some ridiculously good bats from the special cave that is Asad's shop! And let's not forget H4L who (in my opinion) is probably pressing some of the most insanely responsive bats at the moment, plus his clefts that are drying out and almost ready to shape are very special indeed!
In short, I reckon you will be happy whichever you decide on!
