focal length vs. aperture

Hi
I am in the market to buy a telescope. I think I have narrowed it down to 2 telescopes in my price range.
1) 8" (203mm) reflector with 800mm focal length, or;
2) 6" (150mm) reflector with 1400mm focal length.

I understand the greater the focal length the greater the magnification, and;
the greater the apperture the brighter the image.
Both telescopes come with 6.5mm and 20mm eye-pieces.

Any views on which I should buy would be greatly appreciated.

I will probably use it for planets and star cluster viewing, and possibly astro-photography in time.

Many thanks,
Ali
