I currently own a 55-250 and am trying to figure out whether I want to go the 70-200mm route or the 70-300/100-300 route for the L lens. I really enjoy my current lens and its reach, so I'm wondering how noticeable the loss would be to go down to 200, or how noticeable the opposite would be to get an extra 50 for the 300 end. So, I'm looking for comparison shots of 250 vs the 200/300 to get an idea. I have done a comparison myself on the 200 vs 250 with my current lens and there doesn't appear to be much of a difference at all, to my surprise. However, I'm curious about the extra 50 to see if it's just as negligible.
