Trying to make mounted kobold champion - The TTRPG network

Hey as my last character, ranger died in AV, im looking to make kobold champion, but cant decide between two flavors of build: 1. https://pathbuilder2e.com/app.html [https://pathbuilder2e.com/app.html] Champ, shield ally, with summoner dedication, dragon steed form. 2. https://pathbuilder2e.com/app.html [https://pathbuilder2e.com/app.html] Champ with cavalier dedication, mature draft lizard. Eidolon pros: dont take double damage from aoe, spellcasting, fire breathing Eidolon cons: less hp, no “free” actions (tandems). Cavalier pros: more hp, better attacks, better ac later due to feats, free action from mature. Cavalier cons: takes dmg from aoe, will need to be given commands if need to double stride. Imo action economy is better with cavalier, but summoner provides spell casting and versatily… Im lost.
