I thought it would be interesting to record my opinion (or should I say prejudices) about Juniper right before starting with the certifications.
Juniper hardware is a server architecture, with Intel processors. For that reason they cannot deliver near the performance of a Cisco device, which has dedicated hardware.
On the other hand, being based on FreeBSD with routing/firewalling daemons makes possible to use the full power of a Unix shell within the OS.
Let’s see if after the JNCIS-SEC certification they end up convincing me :)
Update: it looks like they have some ASIC integrated for R/S functions. I don’t recall seeing that…
