I know the 70-300L is newer and with better optics and IS system. I have the older 70-300 IS (non-L) and the 300mm IQ is pretty bad. The other option for me is the 70-200 F/4 IS, but after spending a week in San Diego, 200mm on the beach just may not cut it.

I couldn't even get real close shots of bikini-clad women. Sorry if this offends anyone. I've seen sample shots of the 100-400 and they are very good. Same with the 70-300L. What I always hear is from 200mm to 300mm is not THAT noticeable. But from 200mm to 400mm is significantly longer, of course. What to do?

The 100-400 makes more sense because you are distance limited.

The difference between 200mm and 300mm seemed rather trivial when I first experimented at the camera store (seriously, it's like the equivalent of taking a small step forward)...but out in the field, it actually CAN make a difference. And the farther away your subject is, of course, the more difference you will notice.

I chose the 70-300L over the 100-400 due to its higher image quality and lighter weight (win-win for me). I assumed I could possibly even crop the 300mm image to approximate 400mm and still get equivalent quality to what I would have gotten with the 100-400 at 400.

But YMMV. I would try both and see. Basically, your choice will be between extra reach (100-400) and lighter weight (70-300). Also, remember the wide end as well. 70 vs 100 is quite a difference if you need to pull back.

Are you shooting 1.6x or full-frame? When maximum reach is needed, it is REALLY nice to have the 1.6x factor that an APS-C camera gives you.

I take it this is a joke... If it isn't, then you seriously need to take a look in the mirror and decide whether you are a photographer or just a voyeuristic perv masquerading as one.

The 70-300L gives excellent IQ and contrast thoughout its range

I agree. I had a new 70-300L. sold it and got a 100-400L... kind of regret it. The IQ on the 70-300L is far ahead of the older 100-400L. The only problem is it does not take canon TC's... but will take Kenko etc

Well, I actually have both. Maybe seems a little crazy but they are very different lenses in my opinion. If your main interest is wildlife and birds, then the 100-400 is definitely the best choice. For an all-around long zoom that you can keep in your bag at all times, a 70-300mm is much more practical.

I wouldn't want to carry around the 100-400 all day, every day. The 70-300, while a substantial lens, is much easier to manage. So, as with most advice, it depends on what you intend to use the lens for.

The answer is obvious.  You need to either disguise yourself as a bikini-clad girl to get in closer, or you need to construct some sort of "girl blind" to conceal yourself in. 
Or, perhaps you could actually MEET a girl and then you could have her permission to photograph her. :-*

Now that would get me locked away ...... or I would have to have an all over waxing and shave the beard off :-[ :-[ :-[

Do let us know if/when you decide to do it, though; it would make a great photo-op!

Owning both currently, there isn't any real difference in optical quality between them that I can see (on 7D) and I wouldn't worry about that. I'll happily use either at any focal length wide open, when the only time I stop down is if I need more depth of field.

It was mentioned the difference between 200-300mm didn't appear great, that could well be the case if tested at relatively close focus. The 70-300L does suffer from noticeable focal length shrinkage when close focusing, where I can't say I noticed any on the 100-400L.

Aside from that, the differences are pretty much well known, with the 70-300L having the newer IS system, better sealing, and being much smaller and lighter. The 100-400L gets you the extra reach, and love it or hate it, you have the pump action zoom. If you put a gun to my head and say I could only have one of these, I'd pick the 100-400L without hesitation.

I had the 100-400 and sold it to get the 300 f2.8 and the 70-300L.  The 300f2.8 is amazing and is my go to lens when I want the big gun since it takes the 1.4x and 2x well.  I'm much happier with the 70-300L as the walk around lens, lighter, sharper, smaller.  I did not get sharp pics with the 100-400 at 400mm, but it may be just me.

I wouldn't recommend the 300f2.8 as a snooping lens for taking biniki-clad women though as it is VERY obvious.  You definitely need a girl blind to conceal it ;)

I got 70-300L then ungraded the 7F to a 1D4 so got a 400 f/2.8.

I am now hooked on the large whites :) My 1DS3 now has a 200 f/2 glued on - very, very sharp and so much contrast from this combo! Taking portraits is SO good and easy

My walkabout is the 1D4 with 70-300  ;D
