I think it makes sense for you to get an advanced trainer instead of superior. You have to pay a fortune for a superior trainer and you can easily save a lot more with an advanced trainer.
The difference between the two levels is only about 2-3 weeks worth of training a season so your training is not going to take that much of a hit. But that is up to you whether you believe that extra 2-3 weeks training a season is worth the additional amount you are currently paying for your superior trainer
