I would recommend you to take Ajmer as it is now the zone centre and the placement cell will expand in the upcoming years. The reputation of Ajmer is far more than CTAE Udaipur but in the end, I would recommend you to not get into RTU as it has lost its reputation that it had once during RPET.
Hope it Helps... Good Luck!
