After research including official Sena support forum I decided to go for Intercom. Looks like Sena is great, have all new features, however is not waterproof. they say it is some kind of rain proof, but many people just drown the out during their trips. New intercom Urban, Sport and Tour is IP67 waterproof. Also with BT 4.1 and similar spec to Sena 20S.
Will arrive soon, so I'll let you know how reality compare to reviews.
