the platnium used to be priced higher but it came down.
ocz and corsair are both reputable companies. i had good experiences with both.
i'd might favor ocz just a tad but for the two models i showed i would go with the corsair
now that you mention it, OCZ has been great with me also!
4 years ago I moved from the states to Chile, south america, but i brought with me my last built PC. The thing is, my OCZ 500W PSU failed and it was kind of expensive to ship it back, so OCZ solution was to ship me back a 700w GamexStream instead (at the moment it was quite high-end), and I was quite happy with the arrangement.
Kudos for OCZ and their good-willed personnel!

OCZ uses a lot of gimmick stuff so you can have umpteen different choices at umpteen different prices for basically the same RAM. I've tried them twice and RMA'd them for not being at advertised speed/latency.
A bit off topic or out of range price wise, these gave me a good laugh. http://snipurl.com/jn1j4
You can never go wrong with RAM that has red and green "blinky' lights! LOL
"The distinctive heat spreader lets everyone know you aren't someone to mess with, assuming that you let them close enough to your rig to see what you have under the hood."
More like being embarrassed you spent $300 on RAM with blinky lights.
