RAM options

I need the following for my new build:
- 2 x 8GB ddr3 (to keep the option open for adding another 2 x 8GB RAM later on)
- At least 1600 Mhz
- Would be nice to have some overclocking available in needed in the future

I have found the following:
Corsair ddr3 (low profile)

OR

Corsair ddr3 (high profile)

I checked the specifications, but just wanted to check a few things

Few questions:
1) Anyone have any experience this RAM?
2) Is having the higher profile option worthwhile? I guess this helps with the cooling? There is not much price difference between the two.
3) If you feel there are better alternatives for the price (or for a bit more)?

I look forward to your comments.

Thanks
