Do software suites have a competitive advantage over specialised B2B SaaS?

Here is the conundrum: 1. Most of the innovation happening today in B2B software comes from specialised B2B SaaS vendors. 2. On the other hand most businesses probably tend to prefer application suites that are tightly integrated. Examples are SAP, and also new entrants such as ClickUp and Monday.com. Indeed, the fact that most if not all SaaS have public APIs suggests that tight integrations are important. But are the integration options that SaaS vendors have at their disposal enough, or can SaaS benefit from new ways of integrating? Quick show of hands?
