I think the main difference is how you are using them. I have mostly the elcheapo Pinnacle Limits for tightlining, but I have a couple of the B&N Buck's Graphite Jig Poles and there is a significant difference in the weight of the two. The B&M is much lighter and has a more sensitive tip, whereas the Limits have a parabolic flex to them.
If I was single pole jigging or casting I would much prefer the B&M because it is lighter and easier to handle. However, when I am tightlining it does not make any difference to me which I use. I don't have any over 12' either so I can't comment on the longer ones.
