Eyepieces these days, even those with multiple elements have very good throughput due to their high quality glass and coatings. The TV 7mm Nagler T6 and 8mm Ethos are my favorites in that range and one of the reasons is that an object takes longer to drift across their wide fields so there will be less nudging of the scope to keep it in the field. The other advantage is that they have a greater ability to frame multiple objects close by and allow you to see all of a large globular cluster and more of very large bright nebulae.
The advantage of the TAK LE 7.5 is that it does have less elements allowing slightly more light transmission so if you are trying to get close to the theoretical maximum then that would be the way to go.
