I agree with some of the modifications. Squats and deads on the same day is no good. I wouldn't drop the arm work though from 3 sets to 2. I would keep it 3 sets and do 8-15 reps, a little higher on the volume side.
In terms of which routine to do.. I think it depends.. I had some of my best gains on a UL+PPL split. The advantage is the training days are a little less volume because you have 5 days vs 4 to fit in everything. So, if you need a little more volume, and like training 5 days a week I would go for that.
