I use them only for voip numbers, have never used their email, credit card, vpn, etc services. For the voip numbers its been fine. Their android app is tolerable at best, I dont always get notifications for text messages, and theres no group messaging for SMS, which can cause hassles since I use one of their VOIP numbers for work. Id give it like a 6/10, I find it hard to recommend based on my experiences, although Im also not really putting in any effort to switch away from them
Mighty Mighty Bosstones and Reel Big Fish are both classics. Im also a big fan of Madness. For Ska-Punk you cant beat Less Than Jake
