Yes, I watch animes as they air.
No difference with watching a whole series. even the waiting time is the same.
I already tried both, and I don't see any plus value for waiting 13/24 weeks, since it's the same with the between air watchers, heck they're even faster than "whole watchers", since once the final episode is aired "Between watchers" will watch it first, while the "whole watchers" download the Batch.
About the enjoyment, it's the same in the end
"between watchers" will be more "wanting" to watch if the "cliffhanger" is right
Whole watchers won't get that feeling, but they'll only get the "finally I've watched this" feeling.
The appeal for "Between Watchers" IS they're up-to-date, has a fast discussion rate, and will have more time in the end.
Whole watchers, will usually left behind, GET SPOILED A LOT by "between watchers", usually doesn't have a place to discuss since it's cool downed, and they won't have more time, since they're always "backlogging"
