Thoughts on new civs gameplay?

Lithuanian relic bugs and terrifying charge attacks aside, what do you guys think of the new civs gameplay/mechanics/strategies?

Sicilians - UU seems like decent counter to heavy infantry civs, and farm upgrade double effect seems alright but doesn't really feel all that noticeable, their stable and archer units don't seem all that amazing. Spamming their UU from donjons/castles vs goths late game would be a pretty solid counter, but that's the only use case I can come up with off the top of my head (in this regard they're similar to bulgarians). Eco feels standard.

Burgundians - UU seems situationally useful where you can mix in a few with knights and snowball a fight immediately espcially in early castle where numbers are low, but they fall off pretty hard if you're forced to engage for a long time in mass paladin vs paladin fights. The eco boost feels pretty solid but will take some time to optimize. It feels like a weaker cumans feudal TC but have to balance timing of eco upgrades with decent advance times.

Overall - Sicilians feel underwhelming but they've got cool architecture, Burgundians feel decently strong but I'd still pick a top tier knights civ over them and get pikes to deal with castle age cavalier.
