Hi, and thank you for your question. As someone who has experienced all three devices and had them demonstrated in my office prior to adding it to my practice, the only one that impressed me was TruSculpt Flex. That is why I added it to my practice. EMSculpt works via electromagnetic stimulation vs. TruSculpt Flex + which is multi-directional elecrical muscle stimulation. The feeling that they produce when stimulating your muscles is different, and both will be beneficial to you. The difference for me as both a patient, and as a doctor providing the treatment to other patients, is the results that I saw. Both my wife and I saw IMMEDIATE results in muscle growth and muscle tone after doing the TruSculpt Flex treatment. We were left unimpressed with the EMSculpt results we obtained. Once we saw that, we knew it was the device we wanted to offer our patients. Ultimately, you will have to try and see what works best for you. Hope you have a better understanding of which is best from our experience.
