Marketo/Netsuite Middleware

I was wondering if anyone who is integrating Netsuite and Marketo has suggestions of middleware platforms to integrate them? I saw a few from years back but wanted to get an updated take. We are currently using Vertify and are having a LOT of trouble with the sync and their support team in general. One of our Netsuite admins went to session by Jitterbit last year at the NS convention about how they integrate so if anyone has experience or thoughts about the particular platform, please let me know!
