If it makes any difference to you, the Bolivian rams are definitely easier to keep. I've had 4 of them and I still have 2 (2 died, I'm pretty sure from old age since there was no evidence of a disease outbreak in that tank). They don't look too colorful when you see them at the LFS, but they color up nicely once they get used to your tank, as you can see in JC's pic. That's not to say that you can relax on your maintenance, but they're still less finicky. My GBR's just dropped dead on me for seemingly no reason. My perams were perfect, the tank had been established for a few months, and I bought them locally so they shouldn't have been stressed from pH differences. Have you checked out the GBR discussion thread? There's lots of info there that might help you.
Oh, and if you choose Bolivians, good luck sexing them LOL. Just hope you get 1m/2f. I still haven't figured out what sex my remaining 2 are, and I've had them for a couple of years. They've never spawned for me, so maybe they are both the same sex. Either way you go, make sure you provide plenty of hiding spots like caves and/or driftwood. They will appreciate being able to claim territories, and will spend lots of time chasing each other away, at least mine do. They prefer planted tanks, so you're definitely on the right track there.
BTW your rams all look great JC! I can't believe how much those Bolivians have grown!
