It depends on what type of splits you like, what you suck at and what your goals are.
You say you suck at chins, well then you should probably include them in whatever template you go for.
Whatever you go for, remember to keep it balanced. So do atleast a 1:1 ratio between push and pull, so on upperbody days you can do something along this lines:
main pressing movement: 5,3,1.
a pressing movement: a total of 30-50reps.
a row variation: a total of 30-50reps.
a chins variation: a total of 30-50reps.
Offcourse you can do the excercises in a different order aslong as you do the main movement first( though some light sets of rows are great as part of warming up for bench ).
You can also do the rows and chins beetwen setts of pressing etc.
If you choose to do one of the fullbody variations, then the training days will look different offcourse.
In the end its the main movements and the ability to make progress on them thats matters, so aslong as you make progress on them and at same time are able to have balance then you are fine and dandy.
PS. I use at the moment the 2day a week template from the book and its probably some of the most minimalist template out there, but its great so far and its easy to stay focused on it.
