5’11” here on a new shape 2007 Large Heckler – I find it a little short & ride with a 100mm stem & layback post.
I also have a Turner DW Flux in large with a 100mm stem & in line post & find the bike better handling & a comfier ride, this bike is also a bit lighter.
I feel with Turner I’m between the wheels where as on the Heckler I’m positioned further towards the back wheel & have a little lower back pain after a while.
So yes I find the shorter travel better but thats probably more to do with frame size differences between manufacturers rather than travel differences, although I think shorter travel means more XC style & thus a more stretched riding position.
For me I think something like Trek Fuel EX sizing would be a good fit & fall nicely between the 100mm Turner & 140mm SC should one bike replace both.
Try get a test ride on a bike you think suits your requirements, its personal preference at the end of the day.
