VOIP with a mix of soft and hard phones - ring central?

We have about 30 users in 2 offices and we're upgrading our phone system. We have 2 quotes - Ring Central looks great on paper but in doing research I see nightmare stories with support and renewals. Quote 2 (uvoice) is local and the gui isn't as pretty but we've been with them for 20 years and their support has always been outstanding. They are also double the price. WWYD?
