Comparing 2 tables best practice

[MasterSonic]

Hi guys

I have a 2 tables to compare (excel source)

I have an idea what to do with it😎, but I thought maybe you have better/faster way of comparing 2 tables:

1. 2 tables - there is common  ID column ( may happen that one table has more rows tho)
Is lookup option would be better or merge?

2. column names are different ( I have a key in excel ).
Should I renemed them in bulk or there is  way to create 3rd table and use it as a reference.

3. Values in 1 table can be YES NO, in table 2 TRUE FALSE

You recommnend to rename them in power query beforhand or perhaps is more clever way to do it.

Thanks in advance  for any ideas
