Wow, this is a question that can really fracture a community. My two cents, from pretty extensive linux experience and one short Solaris experience: do what aligns more with your IT admin's philosophy. My feel for Solaris is that everything is managed -- there are daemons to watch daemons whose job it is to make sure certain apps don't go down. Linux is a bit less monitored -- "Oh, your apache process shouldn't have gone down? Shit you shoulda had something watching it." Personally, I like the more ad hoc feel to linux. But pick whichever your sysadmin prefers. Solaris, to me, felt like I was being handcuffed.
