OpenBSD platform of choice?

[Daniel Gracia Garallar]

Hi there!

Now that I have to change my little server farm and I'm able to choose a 
new platform, I would like to choose wisely.

It's a matter of fact that Intel x86 is bogus-prone, and after 
experimenting a lot with OpenBSD and listening about the different archs 
since several years ago, I tend to think that most of the delevopers 
have a taste for Sparc derived machines as being more... predictable. 
But of course, no machine is bug free.

So thinking about security and stability, what would be your OpenBSD 
platform of choice?

Keep in mind that in this question price is not a factor. I'm just 
curious about preferences based on CPU features and their implementation 
on OpenBSD.

Regards!
