.....mmmm.....much of the problem may be that we just have too many to fly, and do not get to learn each ones quirks. But, I do think it is interesting to hear folks having FR issues with planes like the 377, F16, Columbia, etc. I have a fairly outdated machine by current standards, and do not have many issues there....and lifejogger, I'm not sure if you are flying from the VC or not, but with the newest ES Cirrus's, you really have to crank down the display brightness in the MFD/PFD to see things more sharply....but as someone who wears bifocals, I do have issues now and then, which is why I bought separate 'reading glasses' to wear while simming.
Now....I take a rather methodical approach to all these aircraft I don't have time enough to fly as much as I should. I actually keep a graph of all my aircraft I fly, and how much time I have in each (there is a log book tool I use that does this easily for me that creates .csv files I can import into Excel). That way, I get to see which ones are being ignored. I highlight the ones that deserve more attention, and fly them exclusively till they start to gather more hours, thus providing myself the opportunity to fly much more of my fleet.....some I have simply forgotten about. More often than not, once I fly these 'ignored aircraft', I wonder why I have done so in the first place. Then I have those fairly new aircraft like the F16 and 377. Once I get some time in others, I'm going to try and concentrate on these two. I love the 377, as my father used to fly KC97's with SAC long ago, so have always had a soft spot for this bird. But man, the aircraft really takes much time to learn, and you really have to be dedicated to it in order to learn the systems...which I do enjoy. So it will get its turn, but only when I really want to dedicate time to it, as it just isn't an aircraft you 'jump in and go'. I really can't figure out what to do with the F16, but I'll figure it out, and will probably fly it totally different than all my others.
Are there some I don't fly? Sure...after several flights, I just cannot get used to the Rutan's cunard aerodynamics while landing, and it has become frustrating to me. Or, the DA Piper Cheyenne which while absolutely beautiful, has way too many bugs for me to give it further hours. The bugs are mostly related to the Trimble, and I'm just kinda 'done with it'. But these cases are actually few. Some simply get ignored, and deserve more time. One of the great things about simming is we get to enjoy all these various experiances which would be impossible in real life.
