Not being a specialist, I would say that the safer is the best option. 
Optimisation flags comes with drawbacks on some codebase.
There was a time, a long time ago, when I compiled the kernel, -O2 and 
-O3 lead me to different misbehaviour.
Being "old" now, I dont compile my kernel anymore ;-)

I know OVH really liked Intel brand, and they provide dedicated servers 
where you can choose many OSes.
That's just what I know.

But I'm certain your feedback would be interesting.

At least, buy your in a store where you have choice *and* where you can 
replace it if ever fails to run with your OS.
Could be more expensive, but...
