My first one is an in-house pipe from a B&M shop (AKA a no-name pipe with the name of the shop stamped in). It’s a bent horn shape.It would help to know what your three pipes are.
For example- if the other two were no name basket pipes bought from a pile of them in a cigar shop - and the new one you like is a nice Castello estate - - that would impact our replies.

The shape is the primary reason why I don’t like it. I find it clenches awkwardly and looks bad on me. The secondary reasons are that the bowl is tapered in such a way where I basically can’t get the last 1/3 of the bowl to stay lit, and the airflow in general isn’t great. I don’t know why I’m unable to smoke it down to the bottom, but it seems like no matter how lightly I pack, tobacco ends up jammed in the tight spot at the bottom.
My second is a Brigham Voyager, which is decent enough with the filter removed. But it’s kind of a heavy pipe and is slightly bent, so again it seems to be awkward for the clench. Brigham pipes have this weird aluminum and wood filter that I immediately removed since I didn’t like the restricted airflow. Given that the filter is gone, it’s like the bore hole at the bottom is too big so I always get tobacco in my mouth as I draw on it to check how tight the pack is. But still somehow the airflow doesn’t seem wide open. Maybe the bore hole is big and the stem hole is smaller?
I also hate that I can’t get a pipe cleaner all the way through to the bowl even with the filter removed.
My third and most recent pipe is a Savinelli Dolomiti 106, which has a smaller-sized bowl, is straight and very lightweight. It clenches perfectly. The airflow is nice and open, and tobacco seems to need relights far less often when I use it. The best way I can sum it up is it has an overall feeling of quality about it. It’s like “oh this is what pipe smoking is supposed to feel like”
