Is the upgrade from kit kat to lollipop worth the memory space usage

[AC Question]

I'm trying to decide if upgrading my galaxy s4 from kit kat to lollipop is virtually bug free and worth the memory space usage?

That's a tough call. LP supposedly has more security/updates, the interface will change somewhat, and possibly some degree of functionality will be added, while some functionality may be removed. You need to research what all the changes are before deciding.

I still run my Note 4 and Note 10.1 2014 tablet on Kitkat 4.4.4. While the Note 4 has been pushed to MM and the tablet has LP available, I find no compelling reason to upgrade the OS on either device. Besides the fact that I despise the "Material design" aspect of LP/MM, I just don't like all the white space of these OS's. However, that's just me. Both my devices work without any issues on Kitkat and to me that's the most important thing.
