i don't think they are incompatible, but they are _different_, and switching between them is like e.g. switching between e.g. cross and parallel system. It opens up some options, and closes others. None of this matters when the connection is great and the dance is working - but it really matters is when something happens and the dance goes wrong - everybody has an ingrained idea what the "safe and predictable" thing is, and where to go to rescue themselves and their partner. And that is where these differences become noticable and make the dance less enjoyable - things get wobbly, and we are trying to save them, but what we feel is making the situation better is making it worse for out partner.
