You asked" can I get better q with electric than fire "is a lot of different questions.
A traditional Cookshack is an electric heating unit that starts wood on fire.
Temp and air control,gives a clean smoke..etc.
You are cooking low and slow with smoke,which can be a definition of bbq.
Cooking with fire,could be hotdogs,marshmellows,hamburgers,etc.
I've cooked a lot on the smallest traditional CS,and now cook on a restaurant size CS 160.
I also cook competitions on FEC s.
I feel I can cook comparable bbq on either.
Each has it's different strengths.
