Ok so just for fun, vote for your favorite lens. Not necessarily the lens you use most, or the one you would have if you could only have one, but just your favorite one, for whatever reason.
Obviously I couldn't include ALL the lenses out there, poll is maxed at 25 choices, so I only put in canon lenses, mostly all L lenses with a few exceptions, no super-telephotos, no discontinued lenses except for 24-70, and no EF-S lenses.
My personal favorite :85mm f1.2L II USM. The portraits I can do with that lens are just mind blowingly beautiful
The 70-200 f4L IS...from your list...it's my second most used lens tho.
The 100 f2.8 non-L mac is my fav, has been for more that a decade...until I get the L

WOW! Impossible for me to answer without adding, "this week" to the answer. If I limit it exclusively to the lenses given in your poll (omiting the version 1 variant of several choices) then my favorite lens THIS week is the 35/1.4.
For family photos, what I do much of the time, and many outdoor photos, the 50mm lens is amazing. It is cheap, sharp, light, and versatile. $100 for 85% of my photos! Can't beat that.
The 70-200 f2.8 IS II is the only zoom I retained in my "arsenal" of Canon lenses. It is my most versatile and most used lens.
The IQ is phenominal for a zoom and continues to provide excellant images. The Canon 1.4TC provides me with added focal length without any degrading in IQ.
Next and tied with 70-200mm is 300mm f2.8IS.
But running a close second are tied the 180mm Macro, 14mm,24mm and 35mm II's.
