Suse has a functioning business model and makes money from real paying customers who want services in return, not just VCs who want more money in return. Docker has a valuation without a way to live up to it, which is scary because we all have to wonder what awful stuff they're going to have to do in order to make enough revenue for their investors to get their money back.
even though it's true that SUSE has a functioning business model, it worth to mention that SUSE belongs now to https://en.wikipedia.org/wiki/EQT_Partners, a global investment organization, and they (EQT) are probably aiming just for a nice exit.
