Upgrading from Fenix 3: Enduro 4 or Fenix (8 or 9) Solar?

Hi everyone.

My trusty Fenix 3 has finally run its course after all these years, and it's time for a massive upgrade. I'm currently torn between the Enduro 4, Fenix 8 Pro Solar, and Fenix 9 Pro Solar.

My main requirements are:

Maximum battery life (I don't want to pack a charger or worry about battery anxiety on long multi-day trips).

Reliability and practicality in the field.

My current activities are regular running and hiking, but I plan to get into trail running very soon.

For those who have experience with these lineups, what would you recommend? Does it make sense to go with the Enduro purely for the massive battery and lighter weight for trails, or will the Fenix (8 or 9) Solar be more than enough for my needs? Also, is the jump to the 9 Pro Solar actually worth it over the 8 for this kind of use case?
