To each their own but if I was recommending, depending on the genre, I feel there are a lot of anime that would blow these out of the water. All forms of DBZ are only watchable for the nostalgia, Familiar of Zero was alright, accel world was under-average as well as the rest of them. I would recommend Kaichou maid-sama to a select few, however the plot of it is pretty average in terms of tsundere and I'd recommend Toradora over it.
