I think you mean to compare KTP and parallel. Kitchen table polyamory means all partners have met and are on friendly enough terms to share a meal "around a kitchen table"
Solo poly is about how I interact with my partners and ktp, parallel, DATD are how your partners interact with each other. So just slightly different categories there, if that makes sense
That's actually the difference between parallel and DADT. In parallel, you absolutely know about your partner's other partners. You just don't usually meet or spendtime with them
Some people also prefer garden party polyamory. Where you have met and see each other at overlapping social events but there isn't actually a desire to build a friendship there
