Yesterday I did a Sentinel 1.5 comparison: OC vs SB. It is hard to decide which one is better. Both are amazing shavers. Very efficient and comfortable shaves. I could stop at one pass with these. I do a very careful ATG pass for a smooth BBS. Maybe because they force me to be cautious, but I don't really get nicks or irritation with these ones. The SB gives way more auditory feedback, and it is easy to control the shave. The 1.5 OC is surprisingly not aggressive. Lots of blade feel, but unless you are going reckless, it is not an uncomfortable blade feel, it kinda guides you towards the best angle, and it is very intuitive while being forgiving of the angle. I will share a picture with the angle I use. I figure that is easier than saying how shallow, neutral or steep I go with them. The photos also show how efficient first pass they are capable of. I think I found razors that will stay with me for the long run. At least one of them for sure, if not all.
