They're both 24/45, but they sure do look a little different.Do the brushes have the same size knots and lofts? The left looks to be a wider diameter knot with a higher loft, although it is difficult to discern from the photo. If so, this too can affect perceived softness and performance.
What's hooked tips? I'm not concerned, just want to learn what it is I like so maybe it will help with my next brush purchase.
