Having given this some very careful consideration (burp!) I have decided to go with Twix. A good Twix has been my chocolate bar of choice for as long as I can remember, and I have had countless arguments over the years as to why its so much better than a Mars or Snickers! So even though the Chunky Kit Kat is a close contender, I feel like I have history with a Twix, whereas the Chunky Kit Kat is a a bit of a newcomer.
May the Chunky Kit Kat forgive me.....
Long live the Twix!!
