IMNSHO, Inflatable are not only for training for larger, they are enjoyable due to the pression they can provide behind the anal ring. The muscles of the anal ring are usually strong enough to squeeze the "balloon", but doing so, it push the air more inside. It feels "fullier", without tiring the entrance apart.

No stress about removal after a long insertion either with a big inflatable: deflate and off it goes!

Traditional plug combines both motion in and stretching.
Inflatable split them, it's a bit different when it's already in and start slowly to expand.
