Fatboy or Slim? And why?

I have a BB (more correctly a Super 109) in my rotation of daily shavers. I have FB’s and Slims in most of their iterations But the 109 is the shaver I like the best. Used to use it as my ‘go to’ to try out new blades. My ‘go to’ now is the Merkur Slant, but that’s another story.
 
yea the long handles bb is a good head shaver, love it and underrated imho
