Is SAAS the promised land for Fp&a careers?

Pondering my next career move here. As someone who's never worked in SaaS (and maybe this is just "the grass is greener on the other side" mentality), I always had the impression that SaaS as the place to be.

Rationale/impressions: 1. SaaS obviously tend to be tech / software companies that pay well and have healthy margins. 2. Skills are transferable from one SaaS como to another. One SaaS subscription model I imagine is pretty applicable to another. 3. ^Job security and flexibility in going from one company to another 4. Calculating SaaS metrics doesn't seem to be rocket science

Are these fair to say ? Any hidden downsides ? Would love to hear from fpa folks in the SaaS space.
