Pick your poison
We moved from Jive (on-prem) to Lithium. Lithium was a great partner and the migration was pretty smooth. we did not like working with Jive as a company (this was years ago so things may have improved).
There are things I really like about Lithium like the reporting (LSI) and permission capability. It's responsive. They have some neat features for surveys and gamification.
Here's the not-so-good: you have to have a Lithium development resource or become one yourself (which for an enterprise large company, the branding and functionality need to be there -- It can't be hacked together. Members represent millions of dollars. making simple changes like we could on Jive is complicated (IMO).
Unless you have a small team or committed volunteers - the platform starts to consume your time leaving the member nurturing on the back burner. User experience at the most basic level, can be a challenge due to resources. Lithium tends to suggest more technology at more cost of course when really what you need is a way to simplify.
I suggest really understanding what it's going to take to 'own' a platform while ensuring your members get the attention deserved, not what is left over once you've added badges.
NOTE: Business value in $$$. Be sure connect your community data to salesforce (or some way to show attribution of revenue or cost savings for community activity). you will save yourself a ton of back peddling when asked - why do we spend 300K a year on this?
