It's all come down to take the best compromise that suit your driving style
Drum setup
- great braking power
- short term heat efficiency
- great brake bias front-rear
- uneven brake shoe wear when heat soaking occurs , on the long therm the brake bias between L-R will suffer
- great amount of time for replacing brake shoes , diferences in the alignment of the brake shoes across the brake drum that which will lead to differences betwen left and right drums braking sensitivity. It's a PITA to get them (almost) similar
- no visual inspection of the brake shoe or drum state
- small amount of aftermaket upgrades
- great setup for small amount of power in a daily
- can take some spirited driving
Disc setup
- good braking power
- long term heat efficiency
- more front bias with this setup , but any load on the rear will make up for this
- even pad wear
- replacing the brake pads and discs is a walk in the park
- great visual inspection of the pads and discs
- debris could get betwen pads and disc resulting a bad experience
- disc are prone to rust in the long run
- great amount of afermarket upgrades and rebuid parts
- great setup for auto x , track , big power etc.
I apologize for some gramar mistakes
