Basses are different form guitar, they do a different job. I'm not sure it is fair to say one is easier to play than the other as there is always something new to find out ...or invent with both !
I am a better guitar player than I am a bass player. That is because I spend 90% of my time playing the guitar and only 10% on the bass. However I enjoy playing both and respect equally those who are good at either !
As for which on is right for you...well that is a question only you can answer !To find out you could borrow/ hire one or the other and find out by playing them.
A word of advice to the wise, there are 10 x more guitarists than bass players so getting good at the base is much more likely to get you a gig then practicing like crazy on the guitar !
