Linq queries vs Lambda queries

foreach (var id in _clientIds)
{
    items.AddRange(
        clients.Where(x => x.ClientID == id)
    );                
}

// rest of the clients
items.AddRange(
    clients.Where(x => !_clientIds.Contains(x.ClientID))
);

VS

foreach (var id in _clientIds)
{
    items.AddRange(from c in clients
                   where c.ClientID == id
                   select c);
}

// rest of the clients
items.AddRange(from c in clients
               where !_clientIds.Contains(c.ClientID)
               select c);
