public class ObjectHelper{
  public static boolean compare(SObject compare, String checkType){
		try{
Schema.SObjectType targetType = Schema.getGlobalDescribe().get(checkType);
			if(targetType == null){
				return false;

			}
		}catch(Exception e){
			//handle exception
		             return false;

}

TEST:

Project__c project = [select id, ownerId from project__c][0];
Schema.SObjectType oType = project.ownerId.getSObjectType();
SObject myObj = oType.newSObject(project.ownerId);
If( ObjectHelper.isType(myObj, 'User')){
  //do something with the User
} else {
	//do something with Group
}
