You have to find yours by yourself, if their's experience doesn't count to you.
I meant that having owned both lenses, which I haven't, you have a step up on most of the rest of us, who have owned one or the other. There is so much info out there, getting pointed in the right direction can be a big help, if for no other reason to know where focus you're own research. Everyone has to do their own research to their own satisfaction, but an informed opinion can save hours.
The research has been most informative.
The most interesting being that using a 55-300 on my K-3 might give me better IQ that a DA* 300 on a K-5 (which my wife shoots with). SInce I expect within a short period of time a K-3 and an 55-300 may be about the same price, that's the kind of thing you want to know when considering an upgrade path.
