Jumping from the S5 over to the Note 4 worth it ?

like the title says, i am currently owning the Galaxy S5 , my question is ,

is the Note 4 worth getting when i have a s5 ? i would like to experience the Note phone as i never had one before and i like the spen thingie looks cool.

did anyone here had a s5 and jumped to the Note 4 ?

i dont really want to get the S6 nor the Note 5 mainly due to no Removable back for battery swapping and the use of msd.
