Cherry shrimp are hardier and generally known to be a beginners shrimp. I have red cherry shrimp myself and a couple of sunkist (orange variant of red cherry I believe)
Tigers can be more expensive because they`re usually more appealing to the eye/different but do require more dedication/care.
Have a google on both and you`ll see what is required for each and that should give you some idea on what you would be able to keep.
