A very loaded question..

Best in what way?

Loss is usually a function of diameter, frequency and dialectric.. and
of course the loss is a linear function with cable length... If that is
what you are after then you have to work out how much you can afford to
lose vs the cost of getting more expensive cable and connectors. Between
"good" brands you will find that there isnt much difference in loss...
The "bad" ones (often cheap) will have a centre conductor that wanders
and imperfect shield weaving.

Quality as in how long it will last in the sun?

In our commercial installs we use Andrew and Belden. Note that I am
talking about coax that is rarely less than 1/2" in diameter. Beyond
water ingress from badly terminated connectors and direct lightening
strikes we are more than happy with them.

Mr Cebik has a goodly array of antenna designs.
(http://www.cebik.com/radio.html) No doubt you could scale a 900Mhz one
or make something a little wide band like an LPDA or corner reflector.
Google also returns a plethora of make yourself 900MHz antennas.
