SQL Server 2012 introduced a sp_describe_first_result_set stored procedure which you can use to compare the table definition.

When we are working with multiple schemas/servers, there are chances of a mistake like the same table having different data types in between the schemas/servers.

In that case, you can check your table definition manual, or you can use other system master tables for comparing the objects.
But using sp_describe_first_result_set, you can easily compare the object than any other option.

Please check below demonstration:

Create a sample SCHEMA:

CREATE SCHEMA test
GO

Create two sample tables:
Create these sample tables in the different schema with different data types.

CREATE TABLE dbo.ABC 
(
	ID INT PRIMARY KEY
	,Name VARCHAR(MAX)	
	,Class CHAR(2)
)
GO

CREATE TABLE test.ABC 
(
	ID BIGINT PRIMARY KEY
	,Name NVARCHAR(MAX)	
	,Class CHAR(2)
)
GO

Execute below sp_describe_first_result_set, and compare the table definition:

EXEC sp_describe_first_result_set @tsql = N'select *from dbo.ABC'
EXEC sp_describe_first_result_set @tsql = N'select *from test.ABC'

Result:
