Are these places the right choices?

Thanks in advance for any reply,
Is it right that the Caribbean side rains less and it is cooler than the pacific?
Should I go visit that area?
What should I avoid visiting, as I only have 5 days and will be driving around in that week.

My plan is...but can be xhanged...
Arrive in PTY, druve to Coronada, Pedasi, Boca, Puerto Armuelles. Should  I pursue that plan, add the Caribbean?

Thanks a lot.
Luiz
