eurail or busabout?

Hey. can anyone give me some recommendations as to choosing busabout
or eurail? i am heading to Europe this summer and my itenary is
germany, poland, czech republic, austria, italy, croatia, france, and
hopefully spain . I wanted to steer away from an unlimited eurail
pass, coz i don't want to be rushed to see everything in a short
time.. i was strongly considering busabout because of unlimited time
to use travel days and it seems to fit fairly well with the itenary..
but reading some previous posts has made me unsure about my choice.
Any advice would be greatly appreciated! thanks everyone.
