well,
this is maybe not an answer but...
I've been through the same reflections, as you are now,
but on AP-c,
I longely hesitated, the Tamron 200-500mm was favorite for me,
seems the lens is really wonderfull optically (?!),
the new OS-sigma's didn't enter in consideration,
as they seem not to be reliable,
so...
last option : canon 400mm5.6 or canon 100-400mm,
of course this would meen I would violate quite a bit my budget !
so how did I made my decision ?
1° of course look at the photozone review of course,
2° have a look at "lensrentals" for a more practical experience...
3° I went "have a look in the bag" of quite some english birders (and read their comments)
4° but not least...went having a look at pictures at Flickr taken with respective lenses, OH WELL !!
finally the last had the stroke ! looking at quite some pics from the tammy...
comparing what was posted of the 400mm5.6...OH WELL !
of course this is not scientiffic,
but in the end I went for the 400mm5.6,
no stabilistion, no zoom, no super-reach,and even wourse : not delivered before my vacation in Friesland!,
on the other hand:
it is L-glas (!), AF-speed is impressioning à nd unbeleavable quite à nd accurate,
metal barel, lens-hood integrated with the lens, quite light (less than 1200gr),
and for sure what can go wrong with such a simple design (only 7 lenses, no IS)
what made the breakthrough were the examples on Flickr however,
I guess one should only show these pictures he is proud of...
OH WELL !!
I must admit however that most-(I don't incude myself)-fixed-focal shooters,
have quite a bit more skills/experience than zoom-shooters,
so this should be relativated but even then...
just have a look.
