Is JOTL more easily replayable than its brethren games?

Basically the title. Gloomhaven and Frosthaven a more linear, with upgrades, quests, buildings and such. I know there’d be issue with the characters themselves, having to keep straight level up choices and perks. Aside from that would there be any issues with replaying old levels or bouncing around from level to level?

Thinking about getting the game and I have two separate groups of friends that would be interested in playing it. That’s what I’m wondering about.
