Would it be around £1.60 on the Coastliner 306 from Newcastle to Silverlink?

Which service is best to get to Cobalt/Siverlink from Newcastle, Stagecoach 22, GNE Cobalt Clipper 309/310 or Coastliner 306/308? Reliability/frequency, fares, journey time, comfort/onboard features, onward connections etc. Thanks.
