Screams in the jumparoo but jumps in the exersaucers?

Meg used to love her Rainforest jumparoo and would jump and dance like crazy in it but over the last two weeks or so, she has started screaming anytime I start to put her in it!  She absolutely hates it! 

However, she has an exersaucer at both of her grandmothers' houses (they keep her while I work) and she loves them!  She plays and giggles and JUMPS in them!  What is that all about! 

Should I just go ahead and pack the jumparoo up?
