I went for the 70-300L for different reasons, but since the link to the crops were posted earlier we can play with them a little. The original poster has a crop sensor body, so we can disregard the full frame corners.

Roughly speaking, I see (70-200 f/4L vs 70-300L):
70mm f/4 on both: win for the 70-200 f/4 which is just sharper all round.
135mm f/4 vs f/4.5: possibly the 70-200 has a slight advantage in the middle, but both degrade away from that
200mm f/4 vs f/5: possibly the 70-200 has a slight advantage in the middle, but it holds on better in the corners
280mm vs 300mm f/5.6: too close for me to call in the middle, but the 70-300 has a slight edge going out where the 70-200 starts showing hints of CA.

From that you might conclude the 70-300's advantage is right at the long end, and if you your needs up to 200mm are critical, then the 70-200 can have a small advantage.

Personally, as wildlife was also mentioned in the 1st post, it's the 70-300 no question. You don't generally want to mess around fitting TC's in the field if you do find yourself needing to go from 70-280. Having the whole range in one go is much more convenient, and for general wildlife you will be finding yourself towards the long end a lot of the time!

While people tend to ask for "the best image quality" what then usually go for is "good enough" and other factors start becoming more important once that is reached. Outside of special applications the 70-300L is more than good enough.

Just for the record on the 70-300L

f/4: 70-103
f/4.5: 104-154
f/5: 155-228
f/5.6: 229-300

I tried both (70-200L f/4 IS + 1.4 TC II as well as the 70-300L) and to me, both lenses feel pretty much equal in terms of image quality (= they are both excellent and work very well on a high-resolution APS-C sensor). I haven't shot any test charts with them, though.

Ended up with the 70-300L because dealing with the TC all the time is just a big PITA...

Sure, it's also true that in most applications you don't really see the difference, but if I spend that much money, I do appreciate getting the sharpest lens possible.

The OP was asking about the 70-300L vs. the 70-200/4L IS + 1.4x TC.  What does the comparison at ~300mm f/5.6 look like?

Didn't even see the TC part.  In that case, I would say it's a wash.  Actually, if my choice would have been 70-200 plus TC or 70-300, I would pick the 70-300.  I have the 1.4 x II and it's a pain in the you know what to carry it with you and attach or detach it in the field.  Image quality is actually not that bad with it, and might be even better with the III version, but I would still pick the 70-300 if my goal was to have a 70-300 range lens.

When I looked at the charts, I was looking at the edges and seeing how out of focus the 70-300 was compared to the 70-200. I didn't think about the fact they were using a FF and the edges would not be that out of focus on a Aps-c sensor.  And as stated above... the TC can become a pain in the butt to keep putting on and taking off. I do want the reach for shooting birds and other wildlife in the area and on vacation. So that was the main reason I was thinking of the two lenses, as I would still like to have to 70mm end for when I do senior photos, which I currently use my friends 28-135 IS standard lens for.... but I seem to be always shooting the photos around the 60 - 90mm range.

Thanks for all the replies

If you like the "60-90mm" range then perhaps also consider an 85mm f/1.8 for some big aperture fun.

LOL: 

I would love to get a prime lens, but I am on such a limited budget, that I really want to get the best zoom for the least amount, as it will be the only lens I will have to use besides my old 18-55mm Series I bundled lens that came with my Rebel XT. I did rent a 70-200 F4 L IS from Lens rental when I went to the Rockies last year and I have saved up enough money to purchase that lens. I just thought that since the 70-300 is only a couple hundred more, I can wait a extra month and purchase that lens instead. I'm sort of on a very tight budget as I am still raising 2 of my three daughters and also am now raising my 2 year old grand daughter from my oldest daughter.

...... You can just post photos taken with one and I can dream that I took them! LOL

Thanks,
Matthew

Wow, Nice photo. Love the owls. We get a few here that I want to shoot and post. My 60D should be able to freeze the bird in flight???

Something to consider: If you are seriously thinking about the 70-300 "L" I would not hesitate very long. Check Canonpricewatch.com and you'll see that with the current rebates, the lens is at an historical low. Rebates end Feb. 4. Who knows when and if we'll see the price that low again?

The 70-200 F4 is also cheaper right now, but not nearly as big of a savings as the 70-300 "L."  Both Adorama and B&H offer six-months no interest, so if you are confident you can pay it off in that time, and that's the lens you want, I wouldn't wait.
