well if ur talking about the characters like woodsman , carver , Gardner or any of those the differences is the time. For example for the carver u only have to wait 2:50 mins for a stamina instead of 3mins. Also another difference is the weapon, vehicle, and gear items on each character they both have different types of attack and defense
Well, I can type a short overview of all characters: Ex-Military, Teacher, Pro Athlete, Lawyer, Doctor and Police Officer are the Standard Characters you can get as a new player. Their weapons and gear have all equal stats. Their Regen Ratios are as follows: Money - 1 hour Stamina - 3 min Energy - 4 min Health - 1:30 min Woodsman/Gardener; Butcher/Carver and Mechanic/Maschinist are unlocked at Level 100. They have increased regen ratios on 2 stats, which are as follows: Butcher/Carver Money - 1 Hour Energy - 3:10 min Stamina - 2:50 min Health - 1:30 Mechanic/Maschinist Money - 48 min Energy - 4 min Stamina - 2:50 min Health - 1:30 min Gardener/Woodsman Money - 48 min Energy - 3:10 min Stamina - 3 min Health - 1:30 min Their Gear is as follows: Butcher/Carver: Cleaver Attack 130 Defense 125 Butcher Smock Attack 125 Defense 130 Freezer Truck Attack 133 Defense 133 Mechanic/Maschinist Monkey Wrench Attack 145 Defense 110 Mechanic Jumpsuit Attack 110 Defense 145 Tow Truck Attack 111 Defense155 Gardener/Woodsman Hedge Trimmer Attack 140 Defense 115 Gardener Apron Attack 115 Defense 140 Mower Attack155 Defense111 How to use them properly: You have reached Level 100 and have 100 UN's and want a new character. Now you first need to check a little list. What is important to you? Money? Battling? Outbreaks? Well, for Money and Outbreaks a Woodsman/Gardener is your character of choice. If it is Money and Battling/Boss Blasting, you should take the Mechanic/Maschinist. If you want to do outbreaks more quickly and want to battle/blast bosses, you should go for the Butcher/Carver. I hope this was helpful.
