When you use the entity framework you can use both. Since you are using EF6 I would suggest using dbSet to perform your queries. IEnumerable is what you get when you realize your query.

Parts of this example come from Entity Framework Working with DbContext[^]

C#

using (var context = new ProductContext()) 
{     
    // This does not execute the query, but rather just configures it.
    // The result is very much like IQueryable.
    var query = context.Where(e => [Something]).OrderBy(e => [Something]);

    // Once you force enumeration of the query you get an IEnumerable back.
    // It is enumerated by a foreach, ToArray, ToDictionary, ToList, or any 
    // linq operator such as First or Any
    IEnumerable<product> results = query.ToList();
}
