I’m a little confused by the question; are you looking for recommendations for clitoral suction-style toys, or any clitoral toy?
The Womanizers are good, and if you’ve tried one successfully already then it should give you a good idea of things you could ‘tweak’ when looking for another (eg. battery life, number of intensities, internal arm for dual stimulation, head size, etc).
However, if you’re looking for something a bit different, Mrs Chimp’s go-to clit toy is her Zumio E. It’s about as precise a precision toy as we’ve got, and can get super intense (only beaten by the Zumio X 
). I did a comparison review of the E and the X awhile back, if you fancy a read?
